SHAR(1)                 NetBSD 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 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
