Actually re-looking at this, with an output flag (-o sgid maybe) it could fit into ps.
ps is not the problem, that bit of code is relatively simple. The real trick is working with proc/readproc.c, specifically status2proc() If I had written this, I would read each line in a while loop and match with a strncmp. This function uses a hash based of the 1st,3rd and 4th letters in the line and then it does a comparison. It's probably a lot quicker. However, to me its a *LOT* more difficult when you want to add another field in the table, like what we want to do here. I think that you have to extract a /proc/##/status file, leave only the lines you want and then run gperf over it. Then take that output and munge it into the code that is there. Not simple, if anyone reading this actually understands gperf (or wants to) they can have a crack at it. I can write the code that then copies the value in the status file and fiddles with the ps flags but that hashing has got me stuck. - Craig -- Craig Small GnuPG:1C1B D893 1418 2AF4 45EE 95CB C76C E5AC 12CA DFA5 http://www.enc.com.au/ csmall at : enc.com.au http://www.debian.org/ Debian GNU/Linux, software should be Free -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
