SHAR(1) | 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
