shar

SHAR(1) 						    BSD General Commands 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.
     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).

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 or files containing magic characters.

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).  Archives produced using this implementation of shar may be easily examined with the command:

	   egrep -v '^[X#]' shar.file
