ARJ is a command-line utility used to create and manage .arj archives. An archive is a collection of files and directories that are stored in a single file. The archive can be compressed to save disk space and can be used to transfer files between systems or to backup files.
The basic syntax of the arj command is:
arj [-options] archive [files]
To create a new archive, use the
a option followed by the name of the archive file and the files or directories to be included in the archive:
arj a archive.arj file1.txt file2.txt dir1/
To extract files from an archive, use the
x option followed by the name of the archive file:
arj x archive.arj
To list the contents of an archive, use the
l option followed by the name of the archive file:
arj l archive.arj
To test the integrity of an archive, use the
t option followed by the name of the archive file:
arj t archive.arj
ARJ supports several options to customize the behavior of the command. For example, the
-m option can be used to set the compression level, and the
-v option can be used to enable verbose output.
The following table lists the available options for the arj command:
