Hi, sorry for my ignorance but I have not done any UNIX for 2 and a half
years and I am trying this from memory (with a few annoying glances through
an awk manual). I am trying to write a simple script which will check files
of a certain type from one directory and make sure they do not exist in a
control file. I have tried a contrived awk piped into a grep after
redirecting the output of an ls command into a temp file ie

ls *.AMD > $HOME/temp
awk -F '{ print $1 }' $HOME/temp | grep -i $HOME/loadctrl | echo $? >>
errtrp

The errtrp file is created earlier in the script. I was then going to grep
the errtrp for the existence of 1 to check that the files from the listing
did not exist in the control file. I am sure one of you guys with a brain
the size of a small planet can instantly see what I am doing wrong here and
hopefully suggest a solution (it just hangs after writing first return code
to errtrp file). I would imagine there is a much easier way to do this but I
am just too rusty to even remember more than about ten commands. It is
something I have to do at work and I may never have any more UNIX
involvement in the future (which means I don't really want to RTFM if I can
avoid it).

Thanks for your time
Dylan.
