unshar - unpack a shar archive SYNOPSIS
unshar [-flag [value]]... [--opt-name[[=| ]value]]... [ file ... ] DESCRIPTION
Unshar scans the input files (typically email messages) looking for the start of a shell archive. If no files are given, then standard input is processed instead. It then passes each archive discovered through an invocation of the shell program to unpack it. OPTIONS
-d dir, --directory=dir change directory to dir first. Before unpacking any files, change the current directory to dir. -c, --overwrite Overwrite any pre-existing files. This option is passed through as an option to the shar file. Many shell archive scripts accept a -c argument to indicate that existing files should be overwritten. -f, --force This is an alias for the --overwrite option. -E split-pat, --split-at=split-pat separate archives on split-pat lines. With this option, unshar isolates each different shell archive from the others which have been placed in the same file, unpacking each in turn, from the beginning of the file to the end. Its proper operation relies on the fact that many shar files are termi- nated by a readily identifiable string. For example, noticing that most `.signatures' have a double hyphen ("--") on a line right before them, one can then sometimes use --split-at=--. The signature will then be skipped, along with the headers of the following message. -e, --exit-0 split archives at "exit 0" lines. This option must not appear in combination with any of the following options: split-at. Most shell archives end with a line consisting of simply "exit 0". This option is equivalent to (and conflicts with) --split- at="exit 0". -h, --help Display usage information and exit. -!, --more-help Pass the extended usage information through a pager. -R [rcfile], --save-opts[=rcfile] Save the option state to rcfile. The default is the last configuration file listed in the OPTION PRESETS section, below. -r rcfile, --load-opts=rcfile, --no-load-opts Load options from rcfile. The no-load-opts form will disable the loading of earlier RC/INI files. --no-load-opts is handled early, out of order. -v [{v|c|n}], --version[={v|c|n}] Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and `n' will print the full copyright notice. OPTION PRESETS
Any option that is not marked as not presettable may be preset by loading values from configuration ("RC" or ".INI") file(s). The file "$HOME/.sharrc" will be used, if present. FILES
See OPTION PRESETS for configuration files. EXIT STATUS
One of the following exit values will be returned: 0 (EXIT_SUCCESS) Successful program execution. 1 (EXIT_FAILURE) The operation failed or the command syntax was not valid. 66 (EX_NOINPUT) A specified configuration file could not be loaded. 70 (EX_SOFTWARE) libopts had an internal operational error. Please report it to Thank you. SEE ALSO
