display ps command line parameters
Hi all, I'm trying to get parameters entered at the Cygwin command line to appear on my ps command, and failing miserably! i.e. I'm running the following process at the command line: program parameter1 In ps -s I get something like: PID TTYSTIME COMMAND 1234 con 09:00:00 /path/program ... but I'd like to be able to pick up the parameter1. So far as I can see it other ps commands on Unix have an -o args option. I've tried every option that seems to be available in Cygwin ps (v 1.11), but cannot get past this wall. Is there a way of doing this through ps (or an alternative) in Cygwin?
