Get the current cpu % usage on your system.

top -p $(pgrep -d , foo)
top '-p' $(pgrep -d ' -p ' foo)
top $(pgrep foo | sed 's|^|-p |g')

pgrep foo

may return several pids for process foobar footy01 etc. like this:

11427

12576

12577

sed puts "-p " in front and we pass a list to top:

top -p 11427 -p 12576 -p 12577
top -b -n 1 | sed 1,6d
top -p `pgrep pidgin`

You can also use different process using comma: top -p `pgrep pidgin`, `pgrep python` but you have to make sure the process exists or you'll get an error

top -p `pidof apache2 | awk '{gsub(/[ ]/,",");print}'`
find . -type f -name '*.php' | xargs cat | sed -re ':top /\/\*.*\*\// { s/\/\*.*\*\///g ; t top }; /\/\*/ { N ; b top }' | awk '$0 !~ /^[\t[:space:]]*($|(\/\/)|(#))/' | wc -l

Of course, the httpd can be replaced with any other process name

I found Flash eating one of my CPUs after resume, the command above will help with that. For optional kicks you can put it into a script in /etc/pm/sleep.d/ (aspect in #swhack wrote this for me)

running top command in batch mode. it is usefull if you want to redirect the output in a file.

tmpfile=$(mktemp) && echo -e 'startup_message off\nscreen -t top htop\nsplit\nfocus\nscreen -t nethogs nethogs wlan0\nsplit\nfocus\nscreen -t iotop iotop' > $tmpfile && sudo screen -c $tmpfile

This command starts screen with 'htop', 'nethogs' and 'iotop' in split-screen. You have to have these three commands (of course) and specify the interface for nethogs - mine is wlan0, I could have acquired the interface from the default route extending the command but this way is simpler.

htop is a wonderful top replacement with many interactive commands and configuration options. nethogs is a program which tells which processes are using the most bandwidth. iotop tells which processes are using the most I/O.

The command creates a temporary "screenrc" file which it uses for doing the triple-monitoring. You can see several examples of screenrc files here: http://www.softpanorama.org/Utilities/Screen/screenrc_examples.shtml

A simple but effective replacement for ps aux. I used to waste my time running ps over and over; top is the way to go. It also allows complex sorting options. Press q to exit "nicely" (Ctrl + C is always an option, of course). Note that the list updates each second, resorting in the process; if you're trying to grab a specific PID, you might be better off with ps.

htop

Alternatively, htop is available, though it may not come pre-installed. htop is slightly more interactive than top and includes color coding, visuals, and a nice interface for selecting and then killing processes. (Thanks to bwoodacre for this great tool.)

top -b -n 1 | awk '{if (NR <=7) print; else if ($8 == "D") {print; count++} } END {print "Total status D: "count}'
