  • Save current layout of top

    'top' has fancy layout modes where you can have several windows with different things displayed. You can configure a layout and then save it with 'W'. It will then be restored every time you run top. E.g. to have two colored windows, one sorted by CPU usage, the other by memory usage, run top top then press the keys <A> <z> <a> <-> <a> <z> <a> <-> <a> and then as you don?t want to repeat this the next time: <W>

    <Shift + W>

  • Use top to monitor only all processes with the same name fragment 'foo'

    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

  • Run TOP in Color, split 4 ways for x seconds - the ultimate ps command. Great for init scripts

    One of my favorite ways to impress newbies (and old hats) to the power of the shell, is to give them an incredibly colorful and amazing version of the top command that runs once upon login, just like running fortune on login. It's pretty sweet believe me, just add this one-liner to your ~/.bash_profile -- and of course you can set the height to be anything, from 1 line to 1000! G=$(stty -g);stty rows $((${LINES:-50}/2));top -n1; stty $G;unset G Doesn't take more than the below toprc file I've added below, and you get all 4 top windows showing output at the same time.. each with a different color scheme, and each showing different info. Each window would normally take up 1/4th of your screen when run like that - TOP is designed as a full screen program. But here's where you might learn something new today on this great site.. By using the stty command to change the terminals internal understanding of the size of your terminal window, you force top to also think that way as well. # save the correct settings to G var. G=$(stty -g) # change the number of rows to half the actual amount, or 50 otherwise stty rows $((${LINES:-50}/2)) # run top non-interactively for 1 second, the output stays on the screen (half at least) top -n1 # reset the terminal back to the correct values, and clean up after yourself stty $G;unset G This trick from my [ http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html bash_profile ], though the online version will be updated soon. Just think what else you could run like this! Note 1: I had to edit the toprc file out due to this site can't handle that (uploads/including code). So you can grab it from [ http://www.askapache.com/linux-unix/bash-power-prompt.html my site ] Note 2: I had to come back and edit again because the links weren't being correctly parsed Show Sample Output

  • Create an alias, store it in ~/.bash_aliases and source your new alias into the ~/.bashrc

    This is useful if you use a shell with a lot of other users. You will be able to run "topu" to see your running processes instead of the complete 'top -u username'. Read more on alias: http://man.cx/alias


    1
    echo "alias topu='top -u USERNAME'" >> ~/.bash_aliases && source .bashrc

  • Shows cpu load in percent

    This version is precise and requires one second to collect statistics. Check sample output for a more generic version and also a remote computer invocation variant. It doesn't work with the busybox version of the 'top' command but can be adjusted Show Sample Output

    top -bn2|awk -F, '/Cpu/{if (NR>4){print 100-gensub(/.([^ ]+).*/,"\\1","g",$4)}}'

    It repeats a command, such as free, every five seconds and highlights the differences

  • Monitor especific process with top

    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 Show Sample Output

  • This command watches the top 10 processes currently taking up the most memory with thread & other info, incase you don't want to use the TOP or HTOP command.

    This is a alternate command I like to use instead of TOP or HTOP to see what are the processes which are taking up the most memory on a system. It shows the username, process ID, CPU usage, Memory usage, thread ID, Number of threads associated with parent process, Resident Set Size, Virtual Memory Size, start time of the process, and command arguments. Then it's sorted by memory and showing the top 10 with head. This of course can be changed to suit you needs. I have a small system which is why Firefox is taking so much resources. Show Sample Output

    watch -n .8 'ps -eaLo uname,pid,pcpu,pmem,lwp,nlwp,rss,vsz,start_time,args --sort -pmem| head -10'

Random quote from Borat
I improved a bit on the original by only using sed and extracting the quote with a matching group. Use -nE for sed on Mac OSX Use -nr for sed on Linux. Warning! The quotes from Borat are definitely offensive.

Rapidly invoke an editor to write a long, complex, or tricky command
Next time you are using your shell, try typing ctrl-x e (that is holding control key press x and then e). The shell will take what you've written on the command line thus far and paste it into the editor specified by $EDITOR. Then you can edit at leisure using all the powerful macros and commands of vi, emacs, nano, or whatever.

print all network interfaces' names and IPv4 addresses
ifconfig can't properly display interface's name longer 9 symbols,also it can't show IPs added thru ip command, so 'ip' should be used instead. This alias properly shows long names, bond interfaces and all interface aliases. loopback interface is ignored, since its IP is obvious

Encrypt and password-protect execution of any bash script
(Please see sample output for usage) script.bash is your script, which will be crypted to script.secure script.bash --> script.secure You can execute script.secure only if you know the password. If you die, your script dies with you. If you modify the startup line, be careful with the offset calculation of the crypted block (the XX string). Not difficult to make script editable (an offset-dd piped to a gpg -d piped to a vim - piped to a gpg -c directed to script.new ), but not enough space to do it on a one liner.
