May 19, 2015 - A Look At The New Commandlinefu
I've put together a short writeup on what kind of newness you can expect from the next iteration of clfu. Check it out here.
March 2, 2015 - New Management
I'm Jon, I'll be maintaining and improving clfu. Thanks to David for building such a great resource!

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Functions: ps rm sort uniq

Applies 'docker rm' to all container IDs that appear in 'docker ps -a' but not in 'docker ps' - i.e. the ones that are not running.

ps -efL | grep <Process Name>

If you want to see your top ten cpu using processes from the browser (e.g. you don't want to ssh into your server all the time for checking system load) you can run this command and browse to the machines ip on port 8888. For example

docker ps -q | xargs -n 1 docker inspect | jq '.[0].NetworkSettings.Ports +{} | map(select(. != null)[0].HostPort) | map("-L \(.):localhost:\(.)") ' | sed -n 's/.*"\(.*\)".*/\1/p' |xargs boot2docker ssh -N
docker kill $(docker ps -q)
docker ps | sed -e 's/ /\+/g' -e 's/CONTAINER ID/CONTAINER_ID/' | tr -s '+' '\t' | q -t 'select c1,substr(c7, 0, 40),c2,c6 from -' | column -t

When you run a lot of containers the built in docker ps output becomes unreadable. This command formats the output to be easier on the eyes.

Requires q (https://github.com/harelba/q) text as data.

Functions: awk grep kill ps sudo

There are times when a X Window server hangs. When this happens, you can log in on a terminal and kill the Xorg process (i.e. the X Server). This one line command will do the trick.

ps aux | grep 'mysql' | awk '{print $6/1024 " MB";}'
ps aux | grep 'httpd' | awk '{print $6/1024;}' | awk '{avg += ($1 - avg) / NR;} END {print avg " MB";}'
ps aux | grep 'httpd' | awk '{print $6/1024 " MB";}'
ps -e -o pid,vsz,comm= | sort -n -k 2

Functions: ps sort

left-most column is PID, middle is virtual memory being consumed, right-most is actual process.

Functions: grep ps

Displays memory usage for individual instances of an application that spawns multiple instances of itself. This command also works on single process applications.

ps -eo etime,pid,pcpu,ppid,args | sed -e '/\[.\+\]/d' -e '/^[ \t]*[0-9]\{2\}:[0-9]\{2\} /d' | sort -k1r

If you have ever been trying to look for a list of processes based on their elapsed time you don't need to look any further.

This command lets you find the list of processes ordered in a reversed order (oldest at the top) that have been running for over an hour on your system. Any system processes are filtered out, leaving only user initiated ones in. I find it extremely useful for debugging and performance analysis.

while ps -p $PID; do sleep 1; done; script2

User: sanjiv856
Functions: ps sleep

Run one script after another in such a way that second script starts after finishing first one. Without using Pipe | or ampercent && i.e. the first process is already running and you want second one to start after the first one finishes. And this can be done in different folder in case the output of second script will affect the output of first script. So run this on any folder you wish to.

Where $PID is the process id of the already running job (add PID number)

script2 is your script you wish to run after first script ends

sleep 1 is sleep for one second (SUFFIX may be ?s? for seconds (the default), ?m? for minutes, ?h? for hours or ?d? for days, read man sleep)

while [ 1 ] ;do ps aux|awk '{if ($8 ~ "D") print }'; sleep 1 ;done
CMD=chrome ; ps h -o pmem -C $CMD | awk '{sum+=$1} END {print sum}'
ps -eo pmem,comm | grep chrome | cut -d " " -f 2 | paste -sd+ | bc

User: Darkstar
Functions: cut grep paste ps

This command will show the sum total of memory used in gigabytes by a program that spawns multiple instances of itself. Replace chrome with whatever program's memory usage you are investigating. This command is rather useless on software that only spawns a single instance of itself.

ps -u marcanuy -o pid,rss,command | awk '{print $0}{sum+=$2} END {print "Total", sum/1024, "MB"}'
2013-11-20 01:21:59
User: marcanuy
Functions: awk ps

Add up the amount of memory your processes are using and display the total. Replace marcanuy with your desired username.

ps -p $$
ps r -A
output=$(ps -ef|grep -i java 2>/dev/null); for w in ${output[@]}; do if [[ $w =~ .*Xmx.* ]]; then result=$(grep -oP "[0-9]+" <<< $w); echo $result ;fi ; done| awk 'BEGIN {sum=0} {for(i=1; i<=NF; i++) sum+=$i } END {print sum}'

This will find all the -Xmx[BIGINT] running on a system, add them up for you and give you the total.
