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.

   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.

OPTIONS

       -s, --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.

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
           Display help message and exit.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
           The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
           User account information.

       /etc/shells
           List of valid login shells.

       /etc/login.defs
           Shadow password suite configuration.
