Examples: This is the order that was used by default in ARJ prior to 2. It is useful when the archive is to be extracted in an older version of ARJ to avoid directory overwrite prompts.
Upon extraction, it forces ARJ to ask if directory attributes are to be overwritten by default, ARJ will always overwrite the directory attributes without asking for confirmation. CFG in its home directory. If found, this file will be parsed and used as a standard ARJ configuration file see manual for details.
CFG, which means that it should take care to delete the output archive itself if rearchiving fails. This is achieved by compressing and storing EAs as a part of file header. You'll have to disable EAs with -2e prior to using -jn, or to recreate the archive if the EAs are precious.
That is, if the EA data is appended to a file which already contains EAs at the time of unarchiving, the file will retain its original EAs. Archived non-critical EAs will not be restored. When an archive is created, only critical EAs will be saved. With no parameters given, it disables EA handling at all.
Otherwise, an expression that follows it is interpreted as a wildcard that limits EA inclusion to a particular EAs. Multiple options can be entered to represent a set of EA names but list files are not allowed. ARJ a documents -2e. ARJ a test -2e. It's wise to specify "-2e. The system EAs start with dot ". If the icon title and so the extended attribute contains line breaks, wildcard characters or other symbols, real filename will be used instead and the.
This option is ignored during extraction. It must be followed by an exclusion EA name specification. The rules are the same as with "-2e".
Also, the two options may work together, providing both an inclusion and an exclusion rule. Yevtushenko, evsi naverex. The presence of EAs is indicated by a " EA Note that this size may differ from the one given when the file is unpacked - the former is the EA structure size and the latter is the space allocated for EA storage.
Many applications are incapable of handling new archive format although this format is fully compliant with the documented guidelines. Known examples of such applications include File Commander v 2.
What's the cause? The system is questioned for the actual EA size during archiving. A: Since folders are represented with directories, you'll have to enable directory storage with -a1 or -hbfd. The best way for it is to specify an arbitrary large value for volume size, e. Try this: create a script you want to to be invoked after the installation completes. ANS You'll make a self-extracting archive with an automatically invoked installation program. ARJ versions that created the Revision 1 header have used a different method 4 compression.
Support for it was dropped in versions 1. ARJ v 2. The intention was to make the stable versions compatible with it. In this case, all of the time fields in the corresponding header are in the UNIX time format, i. Here is a brief overview of this technology. The extended header layout is as follows all values are little-endian : Bytes Description 1 Extended header ID. If set to 0, marks the end of block chain so the header data can be concatenated and processed. Also it provides a way of checking for trashed blocks.
If you want to archive a filename beginning with! EXE and. OBJ files. The " " symbol indicates that the appended name is the name of the response file. In this case, the file is command. The response file symbol cannot be changed. Only one ARJ command line can be processed per response file.
The command line may be split over as many lines as necessary. See the "- " option for help on options with blanks. All other command options must be specified in the response file or in the ARJ environment variable. To better support long filenames, ARJ provides the "- " option to handle the processing of filenames and switch options that contain embedded spaces.
The "- " switch option enables the interpretation of a text line in an ARJ response file as a single token. In other words, when ARJ scans an "- " option, it will process the NEXT text line in the response file as a single token including all embedded, leading, and trailing blanks. ARJ will continue to process each subsequent text line in the same manner. ARJ" for. ARJ also. ARJ files. As of 2. Prior to 2. Then during archival, ARJ would select from its internal list based upon the "-o" and "-b" and "-hb" options.
Now ARJ uses the "-o" and "-b" and "-hb" options while it is building the internal list. The advantage with this method is the need for less memory to handle fewer files. For example, when doing a full backup of the C drive, ARJ builds an internal list of filenames for all of the files on drive C. When doing an incremental backup -b, -b1 , ARJ builds a list of filenames for only the files that have the archive bit set.
ARJ wildcarding can differ according to the operating system environment. TXT, and others. As of ARJ 2. Because ARJ checks for duplicate filenames when necessary, processing over 20, filenames may slow down as the number of filenames processed increase. ARJ processes wildcards most efficiently when specified as separate command line wildcards inclusive of drive letters. This speedup does not work when using listfiles. It is actually an. The "ac" command will add a chapter backup to a new archive or add a new chapter updating to a chapter archive.
Major space savings will result when some files do not change from backup to backup. Adding a new chapter adds a chapter label entry in the archive. Each volume of a chapter archive will be so labeled. There is a limit of chapters per archive. Please note that the "ac" command abbreviation is dependent upon file sizes and file date-time stamps.
Modifying file date-time stamps with no relation to the system time may cause chapter update problems. In addition, changing the system time significantly may also cause chapter update problems. It is actually an abbreviation for the following command and switch option: "y -jb". The "cc" command will convert a standard ARJ archive to a chapter archive. Example: ARJ cc archive For a multiple volume archive, it is necessary to specify the size of the volumes with the "cc" command.
It is actually an abbreviation for the following command and switch option: "d -jb". The "dc" command will delete the last chapter in an archive. The "lc" command will list the chapter labels stored in the archive. This is a quick way to see what backup chapters are stored in the archive and when they were created.
The "vc" command will list the chapter labels and comments stored in the archive. This is a quick way to see what backup chapters are stored in the archive and when they were created as well as any comments about those chapters. You can specify 0 to 64 filename arguments one can be a destination directory.
The arguments can be wildnames. If you specify the "-r" switch recurse subdirectories , ARJ will add all of the files in all of the subdirectories that match the specified wildname. For maximum compression, use the "-jm" switch option.
This filename can be changed with the "-jw" option. The base directory option is ignored by the ARJ b command. You would specify a temporary executable name as the output name and use that name as the DOS command to be executed. Example: ARJ b archive file. You can specify the DOS command string on the command line with the "-jq" option. Switch options which have embedded blanks must be enclosed by double quote marks.
Examples: ARJ b archive file. ARJ will prompt you for each comment. The user will be prompted for up to 25 lines for each comment. A line containing only a [return] will terminate the comment. The user can choose to input comment data from a file by entering the comment filename preceded by an "!
This file is read as a text file. The lines in the text can be up to bytes long. Only the first bytes of the file will be accepted by ARJ. To erase a comment from an archive, type [space] [return] on the first comment line and [return] on the second comment line. To add only the archive comment and not file comments, use the following command: ARJ c archive -z To add only the archive comment at the command line, use the following command: ARJ c archive -zcomment.
The "-jz" option may not be used in the same manner. ARJ a -zcomment. When wildcard selection is not suitable, you can use the "-q" switch to set ARJ to prompt you for deletion for each file selected. These deleted files are physically removed from the archive.
Delete all files in archive ending in ". You can specify the "-y" or "-jyd" options to inhibit the delete prompt. The delete command normally only deletes files of the last chapter in chapter archives. This is useful in synchronizing an archive to a directory along with an update command.
ARJ will prompt the user before overwriting existing files unless the user specifies the "-y" switch. If the user gives a "no" answer, ARJ will prompt for a new filename. If the user enters a single [return] instead of a filename, ARJ will skip the current file extraction.
When extracting a file located on multiple volumes, ARJ may prompt the user with an "Append? This will usually occur with files split across volumes.
You will also need to specify the "-v" switch to set ARJ to continue to the next volume of a series of volumes. See the "-p" switch for more information.
This feature requires that you specify the files to extract and delete. This option actually uses more disk space than a simple extraction because of the temporary archive that is created during the extraction process. You can bypass the abort by using the "-jd" option. Refer to the description of "-jd" for more information. With the "-ho" and "-ho1" options, you can extract files from an archive based upon the success or failure of a text string search. Refer to the description of the "-ho" and "-ho1"options for details.
When updating a file in an archive with a file that is NOT newer and if the -jv option is selected, ARJ will display a message that there is "no change". Please note that only ungarbled files will be garbled by the ARJ "g" command. Example: ARJ g archive -gdinosaur ARJ also includes a "-hg" option to specify the use of a special powerful encryption routine.
There is a "-hg! Some archives created with earlier ARJ versions cannot be "g"arbled. Refer to the "y" command and the "-g" option for more information about garbling.
EXE program. This indicates that the program is probably corrupted. If the program name is not specified, then ARJ will check the current program being executed. Syntax: ARJ j archive archive1. Note that there is no error message displayed by ARJ when using an unsupported switch with the "j" command. The "-d" option IS supported by the "j" command. Note that switches that do work like "-x" select the archives to be merged and NOT the contents of the archives. The display can be paused after each screenful with the "-jp" switch.
The files are listed in stored order. There are no sort options currently. These files are removed when a purge K command is executed.
For text mode compression, the original file size reported by the "l" and "v" commands is the actual number of bytes input. This is usually the MS-DOS file size minus the number of carriage returns in the file, since C text mode strips a file of carriage returns. ARJ will display the count of files selected within an archive that have Windows long filenames. In the space preceding the date-time field, ARJ will display a " " for year , a "1" for the year The "-jv" option will display chapter range values instead of the CRC value if the archive is a chapter archive.
The "v" command will now display Win9x file date-time accessed and file date-time created properties if they exist in the archive. Instead of a simple "G" to indicate that the file is garbled, that field may contain the values "0", "1", "2", "3", or "4". COM version 2. The "m" command adds the selected files to the archive. If the adds are successful, then the added files are deleted.
The move command does not ask permission before deleting the files. Use the "ARJ a -d" command for that feature. The "m" command when used with "-f" and "-u" will delete any successfully added files as well as any files that are already up to date in the archive. At ARJ 2. Directories can ONLY be selected by using the "-a1" option. ARJ will prompt for the new name of each selected file. You can skip changing the name of a particular file by entering a blank line.
As a tip, it is possible to rename chapter labels to a more descriptive name. You may specify the order of files on the command line or you can use one or more list files.
Any files in the archive that are not specified on the command line or in a list file will be placed at the end of the archive in the same relative order that they were originally. No wildcard names can be used as order specifications. The filenames in the list file must be entered one per line. Example: ARJ o archive file1 file2 file3 In the above example, the files "file1", "file2", and "file3" will be ordered first in the archive. Any remaining files will follow those. Example: ARJ o archive!
BAT batch file for an example of this special feature. To facilitate building list files, the "v" command in ARJ will produce special outputs with the "-jv" switch and the "-jv1" switch.
The "-jv" switch will display only the pathnames stored within the archive. No other listing data is displayed. This output can be re-directed to a file for manual sorting into a list file. The "-jv1" switch will display the standard verbose display with a few modifications. No sequential number field will be displayed. No comment field will be displayed. The pathname is appended to the archive file description data instead of being on a separate line.
Displayed just before the pathname field are the file extension and filename. These fields are available so that the user can sort the text lines by date-time, file extension, CRC value, etc.
This function works such that the output file will contain only the file data extracted. This is important for UNIX-like usage.
Example: ARJ p archive manual. There will be no extraneous header information in output. This does not involve any intermediate disk files. However, when redirecting to the printer, ARJ will translate binary files to text, causing possible loss of data. ARJ sets the file date-time stamp of the output stream.
The "-jp" option can be used to pause the screen output as in the "s" command. The "-jv" option will allow the display of IBM graphics characters with the "-jp" option. The "-ja2" option can be used to force the filename to be displayed in the output stream. This can be used by software tools for blind users.
Errors during redirection to disk files will be detected. An archive is protected with the "-hk" option. It is important that an archive be protected prior to the damage. XRJ file , you must specify the "-hk" option along with the "q" command. Example: ARJ q docs -hk repairs archive. When working with a damaged protected archive and the "Abort, Retry, Ignore, Fail" prompt appears, you should select the "Ignore" option. The default is all filenames stored in the archive. This command is useful if you forgot to specify "-e" to exclude paths.
The action prompt can be suppressed with the "-y" switch. The "s" command filters the text to output by truncating at 79 characters per line and displaying '?
The "-jv" option will allow the display of IBM graphics characters. When "S"ampling output is redirected to a file, only one screenful of data is output per file selected. The use of 32 bit CRCs is many times better than the. Example: ARJ t archive -hk u: Update files to archive Update older files in the archive and add files that are new to the archive. Example: arj u software When updating a file in an archive with a file that is NOT newer and if the -jv option is selected, ARJ will display a message that there is "no change".
The "v" command now displays a sequence number preceding the pathname. This number can be used with the "- " option to access specific files within an archive. The "-jv" switch will display only the pathnames to the screen.
The "-jv1" switch will display the archive data in a manner suitable for sorting on various fields for use with the "o" command. ARJ will prompt the user whether to ignore case when searching. ARJ will also prompt the user for the number of lines of context.
If a number greater than zero is chosen, ARJ will display the matched string and the surrounding context with all of the non-printable characters including newlines replaced by question marks. The context lines displayed will be 78 characters in length. When the display context option is chosen, ARJ will inhibit the progress indicator. If the "-jv" is set, IBM graphics characters to will be displayed.
Then, this command will prompt the user for up to 20 text strings to search for within the archive. A count of all matches will be displayed after each individual file is scanned. Search strings are limited to 79 characters. Matches that span archive volumes will not be detected by this string search.
The "-jq" option can be used to supply the necessary parameters to the ARJ w command. You can use the "-hw" options to change the way ARJ displays the filenames being searched. ARJ normally stores pathnames as if they were children of the target directory. Any drive or root directory specifications are stripped before extracting unless the "-jf" switch is specified with the "x" command.
Refer to the description of the "e" command for more information about extraction. The "-hk! This is useful for entering filenames beginning with "-". It is -?
The command "ARJ -? You can also redirect the as in:. This option can only be used on the command line. Normally, in an ARJ response file, blanks are interpreted as token separators.
Tokens are commands, filenames, wildcards, and switch options. However, if ARJ scans an "- " option in a response file, it will process subsequent text lines as single tokens per line. A subsequent "- " option will revert ARJ to normal multiple tokens per line mode.
Example: ARJ text. For example, ARJ will abort with an invalid switch option error if the second "- " above has one or more trailing blanks. The user has the option of retrying the failed operation. This is designed for unattended ARJ use. This handler will intercept errors that produce the "Abort, Retry It can be specified on the command line or via the environment variable.
The option "-! Syntax: ARJ a archive -! ARJ a archive -! It is possible to have multiple labels in one archive. If none is specified, ARJ assumes the current drive unless a specified target base directory has a drive specification. You can delete one or more duplicate labels with the "ARJ d -q archive label" command. ARJ will query you on each occurrence of "label". This "faulty" mechanism allows a file and label of the same name to be added to an archive.
On the list screen, volume labels will be indicated by the "V" under the "T" column. ARJ will display all labels over 8 characters with a ".
However, ARJ will not restore this extra ". For example, Norton's VL. EXE can create labels with lowercase letters. Programs that delete unusual labels must do absolute writes to disk or use a.
A single bit corruption in the program can result in the deletion of ALL files in the root. ARJ currently chooses not to take that risk. For example, the number 1 selects the first file in the archive. This option is useful in selecting files where there are duplicates in the archive.
It is also useful for batch type utilities that need to extract files sequentially from an archive for processing.
Archive menu programs should find this option very useful in processing archives with duplicate filenames. You can specify a series of files with the n1-n8 type syntax. No embedded spaces are allowed. ARJ e archive - 1 4 NOTE that the order number starts from 1 for each individual archive including multiple volume archives.
In other words, the first file in archive. Do NOT mix filenames with the numbers other than the base directory. Example: ARJ l archive - means file to end. This option does not handle split files properly. The "-a1" switch sets ARJ to add any directories in the selected set of matching filespecs to the archive being built.
This switch also selects hidden and system files as in the "-a" switch. Even empty directories will be added. The "l" command will display such directories with a "D" under the "T" file type header. Older releases of ARJ will skip over empty directory entries.
This option is useful for saving software directories with needed empty directories. See the "-hb" option for a newer way of selecting files. The "-b" switch will select only files that have the archive bit set. It will NOT reset archive bits. Under Windows 9x, the use of the "-b" type switch options to reset the archive bit may result in a sharing violation error. ARJ will display the error and then proceed ignoring the error. It does cause ARJ to reset the archive bits of added files.
If the "-f" or "-u" option has been selected, ARJ will also reset the archive bits of files that are already duplicated in the archive. It is useful for setting the archive state so that a subsequent incremental backup will not backup these extracted files. Files will NOT be restored as system, hidden, or readonly.
The "-c" switch will set ARJ to update the archive regardless of the date-time modified time stamps. When extracting files from an archive with the "-y" and "-f" archives all files on. The "-c" switch will set ARJ to extract these older files. Successfully added files will be deleted.
When used with the "-f" or "-u" option, ARJ will also delete files that are already duplicated in the archive. ARJ will prompt the user before deleting the files unless the "-y" switch is specified. Also, you can use the "m" command which does not prompt before deleting the files. This switch will set ARJ to store only the filename component. When updating files within an archive, ARJ uses the full pathname to match against the full name of the selected files. The "-e" and "-e1" option affect this exact matching.
If "-e" is specified, only the filespecs of the selected files will be matched against the full pathname of the files in the archive. If "-e1" is specified, the full pathname minus the base directory of the selected files is used to match against the full pathname of the files in the archive.
In other words, ARJ will only update a file within an archive if the name of the new file as stored in the archive would be identical to the name of the original file stored in the archive.
This switch used during extraction will exclude the beginning characters of the filename. This can be useful for shortening a long output pathname. Examples: ARJ x archive -e10 will exclude the first 10 characters of the output name. ARJ x archive -e4 f: Freshen existing files This switch used with the "e" or "x" commands sets ARJ to only extract newer files from the archive.
This switch used with the "m" command sets ARJ to update only input files with newer dates than the ones in the archive. After the archive has been updated, all updated selected files and all up to date selected files will be deleted. The freshen options when used with the "u"pdate command are interpreted as "-u" options instead. There is a slight limitation to this switch. When processing files that are split across volumes, the size test is skipped and the file is updated regardless.
This limitation does not exist when using versions of ARJ greater than 2. When processing files that are split across volumes, the CRC test is skipped and the file is updated regardless. This is useful when updating archives with text files on a PC and on a network drive from a Unix system.
This switch followed by a password "-gpassword" will encrypt or decrypt an archived file. During a "l" or "v" command, a garbled file will display a "G" after the method number. Example: ARJ e archive -gpassword If the "-g" option is followed by a question mark "? The backspace key can be used to erase characters.
Example: ARJ a archive -g? Using the wrong password during extraction will result in a "Bad file data" or "CRC error" error message. Use the "g" command to garble an already existing ARJ archive.
Please save your password in a safe place. It may be nearly impossible to retrieve your garbled files if you forget your password. The garble option in this version of ARJ has three versions. One is the original version found in earlier ARJ releases. It is compatible with older versions and works like those versions. The second garble version uses a separate encryption module.
GOST uses a bit key and 32 rounds of encryption. This implementation uses the 64 bit cipher feedback mode. This new option is accessed by using the new "-hg" option. This option sets ARJ to use the separate encryption module to encrypt the data. EXE being executed is found. The user may specify the pathname of the module to use. EXE module when encryption is not needed. You simply do not include the encryption module in the archive when not using encryption. This feature works in ARJ 2.
The encryption overlay module is not included with this version of ARJ. The new garble option accepts a password key up to 64 characters long. Excess characters are ignored.
If you need compatibility with ARJ 2. There is no known method to recover the password other than by brute force, which could take a very long time. The longer the password, the longer it would take to "guess" it. ARJ Software, Inc.
This new encryption scheme is not compatible with the "-g" option of pre If you want to maintain compatibility with pre See the SFX. TXT for details about creating an encrypted self-extracting archive.
A variation of the "-hg" option is "-hg! This "-hg! DLL needed that is limited to a 40 bit key size. Only the first 32 characters of a user password are accepted and crunched into a 40 bit key. This algorithm is designed to meet USA encryption export rules. Of the self-extractors, only the multiple volume self-extractors support "-hg!
When garbling or ungarbling an existing archive, ARJ will detect the method of encryption previously used and select that same method without the need to specify the type of encryption. However, if you specify a type of encryption that is not compatible, ARJ will abort with an error message. Refer to the "y" command and the "g" command for more information about garbling. The progress indicator appears during the add, extract, search, and test operations.
The "-i1" option provides a bar type graphical progress indicator for the compression, extraction, and testing type commands of ARJ. This provides an alternative to the simple numeric increasing percentage progress indicator. The "-i2" option provides a combined percentage and bar progress display. This switch is only operative during adds. The "-i6" switch shows the percentage progress of the WHOLE archive build along with a progress bar graph for the current file.
This switch toggles the set of switch characters. The toggle is reset at end at of each separate switch sequence back to the main set of switch characters. For example, "-ja" "-jja" is the same "-jaje" is NOT the "-jae" is the same is not the same function as "-a".
However, as "-a" because of the double toggle. Also, same as "-ja -je". The switch sequence as "-ja -je". BAK" of the original archive file during an update. The original archive will be suffixed with ". Any existing ". BAK" file will be overwritten.
This has no relation to "backup type" ARJ archives. This option does not work for multiple volume archives. For add type commands, this list contains all files that matched the file wildnames given on the command line. Other options do NOT affect the output of filenames to this list file. To get an index file for backup purposes, use the "-ji" option.
