想su到root提示no shell怎么办？

loadysy

我把/etc/passwd文件里的root的/sbin/sh改成/sbin/csh了，就不让su到root了，提示no shell,root的shell不能改吗？我得怎么办啊？各位大虾救救我！

try not modifying root shell on /etc/passwd, or it\'ll cause unexpected issues, e.g., wrong root\'s shell entry might causes a unix system unbootable.

光盘启动，到单用户，挂接根分区，把SH改过来就可以了。

/sbin下没有csh！ root的shell是/sbin/sh，不要改！
改回原来那样不就行了吗？

root的shell也不是不能改，但千万不要直接改/etc/passwd文件。可以在root的.profile文件中执行/bin/csh。

注意一下，/sbin/sh和/ ...

Good!!!!

I encounter this problem on solaris 10, it\'s really annoy me, but soon I solve it, it\'s very simple:
on booting, when some text show up to you to choose between \'B\' and \'I\', just type \"b -s\", and then type root password, and then just edit /etc/passwd, the line about what root shell should be, make sure your shell program is correct this time.

刚找到这一段，和楼上的一样：

Good news is, if you are running Solaris 9,
there is fallback shell if you stop the machine
and boot it into single user with boot -s
Bad news, it doesnt work in previous releases.

There you have to take your Solaris CD, put it in
boot with: boot cdrom -s
when its up do a mount:
mount /dev/dsk/c0t0d0s0 /a
set TERM=vi
export TERM
vi /a/etc/shadow

remove everything between first and second colon
so it looks like this
root:: and leave the rest as it were

Have fun *L*

do an: umount /a
and reboot the system

Sorry, no other way to do it

我也出现了这个情况，解决办法：
用sun安装盘引导，把硬盘（fsck后）mount到/mnt下，然后vi /mnt/etc/passwd，修改相应的shell。
ok!

完啦，看到这里一篇文章，说在安装Unix后的修改配置，把Root的Shell改成bash，在passwd 文件中改，结果就写成了/sbin/bash
重新用root login,说是no shell, 无法进入，
在本地用root也无法login,其他几个帐号可以登录，可是都不是Superuser，

怎么办？难道我非得重新装Solaris？

看看你的SHELL是什么，如果是C shell,则使用.login

谢谢大家~！我还想问一下，我在.profile中的设置，. ./.profile这样可以生效，但在重新连接就不生效了，怎样才能永久生效呢？
