/usr/lib/... file coruption

[Carlo Henrico_1]

I somehow got it right to corrupt the /usr/lib/lib2.c file and now nothing works. I cannot do ll, cp, mv etc. The system is currently useless. I cannot even ftp to it.

I do have a backup copy of the file on the server, and I am sure a normal cp would have done the trick, however even cp looks for the shared lib2.c file.

Any ideas how to get out of this one please?

Thanks

Carlo

Hi Carlo,

You are in a bind.

We can take advantage of 2 commands in /sbin:
cat or mv (sbin/mv is not the same as /usr/bin/mv).

Try this:
/sbin/cat < goodlibcopy > newlib

or
1) /sbin/mv badcopy safecopy
2) /sbin/mv goodlibcopy newlib

If it were me, I would come up in single user
and do an /sbin/mount /usr.

Hope this helps, Clay

Thanks Clay, that was excellent. /sbin/mv did the trick, and suddenly all is well again.

Much appreciated

Carlo
