名称
chsh - 更改登录 shell
大纲
chsh [选项] [登录]
描述
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.
选项
The options which apply to the chsh command are:
-h, --help
显示帮助信息并退出。
-R, --root CHROOT_DIR
Apply changes in the CHROOT_DIR directory and use the configuration
files from the CHROOT_DIR directory. Only absolute paths are
supported.
-s, --shell SHELL
用户的新登录 shell 的名称。将此字段设置为空会让系统选择默认的登录 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.
注意
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.
