pyproctools is a set of various command line tools to get information from the /proc filesystem. It is based on the proctools utilities of Solaris. The commands include pwait, which waits for the specified processes to terminate; pstop, which stops each process (with SIGSTOP); pcont, which continues running a previously stopped process (with SIGCONT); pfd, which shows the open file descriptors for each pid; and pldd, which lists the dynamic libraries and other files mapped into each process.
