shell的chsh -l为什么用不了?

我使用chsh的时候
输入:chsh -l
结果是:
chsh: invalid option -- l
用法:chsh [选项] [LOGIN]

选项:
-h, --help 显示此帮助信息并退出
-s, --shell SHELL 该用户帐号的新登录 shell

这个究竟是什么回事哦?
man chsh的时候显示有chsh -l这一项的啊!

附注:我用的是ubuntu 8.04

呵呵,可能是man版本和程序版本不一样吧。
估计你是中文的man 吧,你可以 man -a chsh ,中文man退出后有原版英文man的。

我的man
CHSH(1) User Commands CHSH(1)

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.

-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.

SEE ALSO
chfn(1), login.defs(5), passwd(5).
