chsh

CHSH(1) 							   User Commands							   CHSH(1)

NAME

       chsh - change your login shell

SYNOPSIS

       chsh [-s shell] [-l] [-u] [-v] [username]

DESCRIPTION

       chsh is used to change your login shell.  If a shell is not given on the command line, chsh prompts for one.

       chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries.

OPTIONS

       -s, --shell shell
	      Specify your login shell.

       -l, --list-shells
	      Print the list of shells listed in /etc/shells and exit.

       -u, --help
	      Print a usage message and exit.

       -v, --version
	      Print version information and exit.

VALID SHELLS

       chsh  will  accept  the full pathname of any executable file on the system.  However, it will issue a warning if the shell is not listed in
       the /etc/shells file.  On the other hand, it can also be configured such that it will only accept shells listed in this	file,  unless  you
       are root.

EXIT STATUS

       Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.

SEE ALSO

       login(1), passwd(5), shells(5)

AUTHOR

       Salvatore Valente <svalente@mit.edu>

AVAILABILITY

       The chsh command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
