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.

NAME

       chsh - change login shell

SYNOPSIS

       chsh [-D binddn] [-P path] [-s shell] [-l] [-q] [-u] [-v] [user]

DESCRIPTION

       chsh  is  used  to  change  the	user login shell.  A normal user may only change the login shell for their own account, the super user may
       change the login shell for any account.

       If a shell is not given on the command line, chsh operates in an interactive fashion, prompting the user  with  the  current  login  shell.
       Enter  the  new	value  to change the field, or leave the line blank to use the current value. Enter none to remove the current value.  The
       current value is displayed between a pair of [ ] marks.

       The only restrictions placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker  is  the  super-
       user, and then any value may be added.  An account with a restricted login shell may not change their login shell.

       This version of chsh is able to change the shell of local, NIS, NIS+ and LDAP accounts , if the permissions allow it.

OPTIONS

       -D, --binddn binddn
	      Use  the	Distinguished  Name binddn to bind to the LDAP directory.  The user will be prompted for a password for simple authentica-
	      tion.

       -P, --path path
	      The passwd file is located below the specified directory path. chsh will use this files, not /etc/passwd.  This is useful for  exam-
	      ple  on  NIS master servers, where you do not want to give all users in the NIS database automatic access to your NIS server and the
	      NIS map is build from special files.

       -s, --shell
	      Specify your login shell.

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

       -q, --quite
	      Don't be verbose.

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

	   --help
	      Print a more verbose help text and exit.

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

FILES

       /etc/passwd - user account information
       /etc/shells - list of valid login shells
