shar -- create a shell archive of files
shar file ...
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).
shar makes no provisions for special types of files or files containing magic characters.
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
The shar command appears in 4.4BSD.
It is easy to insert trojan horses into shar files. It is strongly rec- ommended 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 4.4BSD June 6, 1993 4.4BSD
