shar
—
create a shell archive of files
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). Archives
produced using this implementation of shar
may be
easily examined with the command:
egrep -v '^[X#]' shar.file
