Listing and PIDs Each process has a unique number, the PID. A list of all running process is retrieved with ps. # ps -auxefw # Extensive list of all running process However more typical usage is with a pipe or with pgrep (for OS X install proctools from ): # ps axww grep cron 586?? Is 0:01.48 /usr/sbin/cron -s # ps axjf # All processes in a tree format (Linux) # ps aux grep 'ss[h]' # Find all ssh pids without the grep pid # pgrep -l sshd # Find the PIDs of processes by (part of) name # echo $$ # The PID of your shell # fuser -va 22/tcp # List processes using port 22 (Linux) # pmap PID # Memory map of process (hunt memory leaks) (Linux) # fuser -va /home # List processes accessing the /home partition # strace df # Trace system calls and signals # truss df # same as above on FreeBSD/Solaris/Unixware Priority Change the priority of a running process with renice. Negative numbers have a higher priority, the lowest is -20 and 'nice' have a positive value. # renice -5 586 # Stronger priority 586: old priority 0, new priority -5 Start the process with a defined priority with nice. Positive is 'nice' or weak, negative is strong scheduling priority.

Make sure you know if /usr/bin/nice or the shell built-in is used (check with # which nice). # nice -n -5 top # Stronger priority (/usr/bin/nice) # nice -n 5 top # Weaker priority (/usr/bin/nice) # nice +5 top # tcsh builtin nice (same as above!) While nice changes the CPU scheduler, an other useful command ionice will schedule the disk IO.

This is very useful for intensive IO application (e.g. You can select a class (idle - best effort - real time), the man page is short and well explained. # ionice c3 -p123 # set idle class for pid 123 (Linux only) # ionice -c2 -n0 firefox # Run firefox with best effort and high priority # ionice -c3 -p$$ # Set the actual shell to idle priority The last command is very useful to compile (or debug) a large project. Every command launched from this shell will have a lover priority. $$ is your shell pid (try echo $$). FreeBSD uses idprio/rtprio (0 = max priority, 31 = most idle): # idprio 31 make # compile in the lowest priority # idprio 31 -1234 # set PID 1234 with lowest priority # idprio -t -1234 # -t removes any real time/idle priority Background/Foreground When started from a shell, processes can be brought in the background and back to the foreground with [Ctrl]-[Z] (^Z), bg and fg. List the processes with jobs.
