What I'm trying to do is look at a list of users, and check to see if each exists. If they do, do some more stuff, if they don't, drop them into an error file.
So, my user list is:
foo - exists
bar - does not exist
blah - does not exist
K, so, here's the script:
I am obviously going to do more. The issue is, the output from id ends up outputting to the shell, rather than "blah". So, in the case of bar and blah, I get:
"id: bar: no such user
id: blah: no such user"
output to the shell. Where, I'd THINK that I'd get the output:
"blah
