Hello

I have moved a critical lib from its location, so all programms linked to libc dont work .

I still have two shells on the machine, bash and ksh

The only thing I see is copying back the lib, but of course : dd, cp , mv etc are dead .
So i tryed a loop with read ...
{^Jwhile read line^Jdo^Jecho $line^Jdone } < /lib/TOTO.a.old > /lib/libTOTO.a

but it doesnt work because it s a binary file .(i tryed it elsewhere, the filesize doenst match ...)

Any idea ?

basically I need to copy back the file with ksh/bash builtins commands only

Thank you in advance .

If you are lucky you may have a statically linked mv in /sbin... What OS?

you could also boot a livecd of some sort and fix it from there.

rebooting is not an option , so no reinstall , thnx anyway

the bins in /sbin arent static bins thanx to IBM !!! (aix5.2)

from now on i will always stick a statically linked busybox on all my servers !!

Given the bad shape of your system, rebooting is in fact your only option. Your server is doomed to crash sooner or later anyway.
You'd rather say: from now on, I will refrain to mess with critical files on my servers ...

Well it s a test server for learning as you see

But if the read command works with binary files , the server would have been fixed

for busybox ... critical files can get messed up by other than you (progs/corruped FS ... a scipt gone wild on weird variables .... )

also can anyone tell me if i can get mapfile to read binary files correctly ?
then echo ...



thnx

What if you export the LD_LIBRARY_PATH environment variable (to the directory where the libc library has been moved to) of your shell ( should be LIBPATH on AIX, I *guess*) and then try to exec the cp or mv programs?
