修改了PASSWD把登陆的SHELL给改错了结果ROOT无法登陆，可有办法补救啊？？

[XJL1981]

给位大哥，由于小弟想把ROOT的默认SHELL改为CSH，于是去修改PASSWD文件，结果没看清把默认的SHELL改成了CHS，导致登陆的时候显示无法找到SHELL登陆，进不了SHELL我无法再改回原来的SHELL。我还有个USER的帐号可以登陆到BASH但却没有权限修改PASSWD文件，想在LIUNX下MOUNT FREEBSD的分区修改却不知道怎么MOUNT。各位大哥给小弟想个办法啊，很急啊，我不想重装系统啊，我机器里有三个系统一重装就要都重搞。帮帮我啊！！！！

试试将csh文件复制一份，名为chs，再进ROOT试试.如果没有权限那只有用同样的UNIX做一张应急盘了。

估计只能用应急盘引导后再修改了。

引导时能进单用户吗？在
Hit [Enter] to boot immediately, or any other key for command prompt.

Booting [kernel] in 10 seconds...
提示时按空格，然后执行boot -s试试。

看来你只有用应急启动了，用linux安装光盘，选择linux rescue,在不使用root登陆shell的情况下可对Linux系统文件进行修改

[shongyu]

At this prompt type 'boot -s' which will get you into single
user mode. From there 'mount -a' to mount all the drives r/w.
You can remount just the root partition if you like, but this
will be easiest. Then use passwd to change root's password
to whatever you want.

使用FreeBSD Disk 2引导
mount 分区修改passwd

BUT......
You should NEVER change root shell!http://www.xs4all.nl/~hanb/documents/change_root_shell.html

[Nvram]

You must use root shell even in single user mode!
but the problem is the root shell can not be found.

[fierygnu]

freebsd此时会忽略/etc/passwd文件。
