NAME

shar — create a shell archive of files

SYNOPSIS

DESCRIPTION

shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands. Parent directories for file operands are created as needed. File and directory permissions are restored.

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. It is not intended for binary files containing NUL bytes.

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).
