shar
SHAR(1) BSD General Commands Manual SHAR(1) NAME
shar -- create a shell archive of files SYNOPSIS
shar file ... DESCRIPTION
shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands. Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly). shar is normally used for distributing files by ftp(1) or mail(1). EXAMPLES
To create a shell archive of the program ls(1) and mail it to Rick: cd ls shar `find . -print` | mail -s "ls source" rick To recreate the program directory: mkdir ls cd ls ... <delete header lines and examine mailed archive> ... sh archive SEE ALSO
compress(1), mail(1), tar(1), uuencode(1) HISTORY
The shar command appeared in 4.4BSD. BUGS
shar makes no provisions for special types of files or files containing magic characters. SECURITY CONSIDERATIONS
It is easy to insert trojan horses into shar files. It is strongly recommended that all shell archive files be examined before running them through sh(1). Archives produced using this implementation of shar may be easily examined with the command: egrep -v '^[X#]' shar.file BSD
