help: i made a really dumb mistake..

Edwin R. Rivera_1 — Tue, 04 Sep 2001 19:52:50 GMT

i was moving/symlinking ksh around on a new a400 HP-UX v11.0 box i got in today so its location would match up with the entry in the NIS passwd map, and sure enough, i rm'ed the binary.

i know, i know, terrible... problem is, since this box is literally "just out of the box", i haven't had a chance to dump the filesystems to a tape yet.. so i can't restore the binary.

what's the EASIEST way to get a copy of that binary? is it on a CD somewhere ? i checked kornshell.com but the process looks a bit involved and i don't want to install a bunch of unnecssary stuff on a brand new production box.

thanks in advance for any help you can provide.

regards,

Edwin,

Welcome to the "Fat Fingers" club, of which I'm guessing everyone on these forums is a member.

I was wondering if it wouldn't be as easy as downloading the latest ksh patch from HP's site and installing it.

Before you log out, verify that at least your root account isn't looking to use ksh as its primary shell, otherwise you won't be able to log back in without rebooting and editing the /etc/passwd file.

i tried copying the binary from an a180c (32 bit) HP-UX v11.0 to my a400 (64 bit) HP-UX v11.0 and it worked fine.

i'm just posting this for fyi purposes for those interested in the thread.

Edwin,

This is hopefully a link to the latest ksh patch for 11.0.

Hi Edwin,

See if you have a file called /usr/bin/rksh
you can copy this file to ksh,
cp /usr/bin/rksh /usr/bin/ksh
chown bin:bin /usr/bin/ksh

-HTH

thanks ramesh,

i was playing with that before, but it gave me warnings about being a "restricted" korn shell. i'll have to read up that one...

Hi Edwin,

i know rksh is restricted ksh, but if you look at the inode numbers it is the same executable and depending on how is is invoked the restrictions come into effect.

Hi Edwin,

Rather than cp, creating a hard link may be a better idea (that's how the original files are, on any other system do a "ls -ail /usr/bin/*ksh" )

ln /usr/bin/rksh /usr/bin/ksh

If you have the installation CD you can copy this binary from OS-Core/UX-CORE/usr/bin
directory.
