I am running a Ruby command line script (rufus.sh)which ultimately calls Thread.new, which spawns a UNIX process as shown below. I run this script for more than 1 directory as the output of the ps command shows below. The last (right most) column below is COMMAND (COMD) which is essentially  the name of the process. The problem is that COMMAND doesn't include the working directory (the current directory when the process was launched). What is the best way to figure that out or include it in COMMAND?

What's the best way to determine the working directory for UNIX process using 'ps'?
command line;shell script;process;ps;ruby
I'm not sure if that answers your question, but the pwdx could give you the current working directory of any process.Like this:pwdx <PID>You could also do what Ulrich Schwarz said and run ls -l /proc/PID/cwd
