SHAR(1) MachTen Reference 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. Di-
rectories 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).

SEE ALSO
compress(1), mail(1), uuencode(1), tar(1)

BUGS
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 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

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

HISTORY
