Finding the CWD (current working directory) of a running process

Luckily, due to the UNIX philosophy of "everything" is a file, makes it rather trivial to find what the current working directory is. You just need to look at the symbolic "cwd" link under the process directory:

# ls -al /proc/[process number here]/cwd lrwxrwxrwx 1 build build 0 Oct 18 12:29 /proc/2506/cwd /root/run
