What is the .SHAR File Extension?

.SHAR File Extension Description:

The file extension .shar refers to the compressed archive generated under the UNIX Operating System platform. SHAR is actually an abbreviation for the UNIX SHell ARchive tool, which produces the file extension .shar in relation to its operation of compressing one, or several files in a single archive.

Unlike many archivers (especially those that are run under the Microsoft Windows Operating System environment), the .shar file extension is actually generated by what is classified as shell script that recreates the specified files once the command is executed. Directories are exempted from the program's recreation process. The file extension .shar can be categorized as a self extracting compressed file, which requires the UNIX Bourne shell's presence to function properly.

The .shar file extension is a pure text file, which unlike other text based formats is capable of execution. To unshar (unpack) compressed .shar file extension, the instructions sh must be typed at the command prompt, followed by the archive's filename. There are however, some unpacking utilities that have been generated to simplify the decompression process, but the reliability of these tools is still suspect. Being classified as a shell script, the file extension .shar is capable of duplicating any function that is inherent in any UNIX based shell script.

The file extension .shar has also helped in the development of other compression utilities like the VMS_Shar, which built on the foundation provided by the UNIX Shar, and is frequently utilized for the distribution via email of formatted source codes. Being a command line driven program, the file extension .shar is created by typing the most basic command on the prompt, which is SHAR. Other options can be added to the basic command like the -S option, which will create a file extension .shar that will implement a text format to allow it to be sent via email.

Other options those are associated with the SHAR compression tool, which produces the file extension .shar, includes -O, which is used in conjunction with the -L, as well as the -N, which is paired with the -A option. Majority of command line options of the program are single letters, except for -help, --no-i18n, --print-text-domain-dir and -version, all of which have no short format representation.
