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).
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 appeared in
4.4BSD.
shar
makes no provisions for special types
of files or files containing magic characters.
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).
