Um. I feel silly asking this. But I can't work it out.
I want a shell script to run as another user. I always thought this was easy
to do with the setuid bit, but never tried it before. I read "man chmod" and
found this:
.....
4000 (the setuid bit). Executable files with this bit set will
run with effective uid set to the uid of the file owner.
.....
s The set-user-ID-on-execution and set-group-ID-on-execution
bits.
....
And off I went. I wrote a shell script to output the current uid. I chown'ed
it to another user. I "chmod +s"ed it. I ran it.
It didn't work.
