CHSH(1) User Commands CHSH(1)NAMEchsh - change login shell
SYNOPSISchsh [-s login_shell] [user]
DESCRIPTIONchsh 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 super user may change the login shell
for any account.
The only restriction 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 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.
OPTIONS
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.
