shar

A Unix utility that removes e-mail and news header lines from its input, and feeds the remainder (which is presumed to be a shar file) to /bin/sh to unpack it. unshar is designed for unpacking archives directly from the news or mail systems simply by piping a message into it.

<tool, file format> ("Shell archive", after ar and tar) Any of the many Unix programs that creates a flattened representation of one or more files, with the unique property that it can be unflattened (the original files extracted) merely by feeding it through a standard Unix shell. The output of shar, known as a "shar file" or "sharchive", can be distributed to anyone running Unix, and no special unpacking software is required. Sharchives are intriguing in that they are typically created by shell scripts; the script that produces sharchives is thus a script which produces self-unpacking scripts, which may themselves contain scripts. The disadvantage of sharchives are that they are an ideal venue for Trojan horse attacks and that, for recipients not running Unix, no simple un-sharchiving program is possible; sharchives can and do make use of arbitrarily-powerful shell features and other Unix commands. Different implementations of shar vary in sophistication. Some just uuencode each input file and output commands to uudecode the result, others include extensive checking to make sure the files have been transferred without corruption and that all parts of a multi-file sharchive have been unpacked. The unshar utility strips off mail and news headers before passing the remainder of its input to sh. (1996-10-18)

In the Unix operating system, shar (an abbreviation of shell archive) is an archive format created with the Unix shar utility. A shar file is a type of self-extracting archive, because it is a valid shell script, and executing it will recreate the files.

The File URI Scheme is a URI scheme defined in , typically used to retrieve files from within one's own computer.

<file format> The kind of data stored in a file. Most modern operating systems use the filename extension to determine the file type though some store this information elsewhere in the file system. The file type is used to choose an appropriate icon to represent the file in a GUI and the correct application with which to view, edit, run, or print the file. Different operating systems support different sets of file types though most agree on a large common set and allow arbitrary new types to be defined.
