Okay, question, first: Did you do: rm -Rf /bin /sh OR rm -Rf /bin/sh ?? Notice the space inbetween the /bin and /sh on the first one. If you executed the first one, you're pretty well hosed - you're going to need to reinstall several packages to get the files back into /bin. If you executed the second one, read on... If you executed ln -s /bin/sh /bin/bash, and the command succeeded, then you have almost certainly wiped out bash with a link to the non-existent /bin/sh. With the ln command the first path is the existing file and the second path is the link. Since you've removed /bin/sh, linking /bin/bash will erase the /bin/bash file and replace it with a link to /bin/sh, which doesn't exist. So, at a minimum you need to reinstall bash. You'll likely need to boot with a rescue CD for this. -Nick On Wed, 2011-01-26 at 20:49 +0800, Huang Yogi wrote: > Dear all > > > After I doing: rm -f /bin /sh ,my pc(Debian) can not work anymore, > > I try to do: ln -s /bin/sh /bin/bash, but it doesn't work; > > > after reboot it shows cannot > execute /etc/init.d/rcS ; /etc/init.d/rc... > > > > could you help me how to fix this problem!! > > > Thank you so much!!! > > > Best regards, > Yogi Huang > > > > ______________________________________________________________________ > From: chi7396@xxxxxxxxxxx > To: todd.deshane@xxxxxxx > CC: xen-users@xxxxxxxxxxxxxxxxxxx > Subject: RE: [Xen-users] Mutiple virtualmachines Live migration at the > same time with Xen > Date: Thu, 23 Dec 2010 13:04:12 +0800 > > The lack of memory caused the problem!
