Ask HN: Share your top 10 linux commands

7 points by giis ↗ HN
Today I came across interesting post which displays top 10 commands from history file.

$ history | awk '{CMD[$2]++;count++;}END { for (a in CMD)print CMD[a] " " CMD[a]/count*100 "% " a;}' | grep -v "./" | column -c3 -s " " -t | sort -nr | nl | head -n10

Here is my results:

     1	135  13.5%  vim

     2	133  13.3%  gcc

     3	122  12.2%  ls

     4	52   5.2%   cd

     5	47   4.7%   less

     6	43   4.3%   grep

     7	38   3.8%   exit

     8	35   3.5%   cat

     9	29   2.9%   python

    10	25   2.5%   sudo

My results vary pretty dramatically depending on which of my history files I point it at, as expected (I separate them by context).

It seems like this'll be warped by a couple things, though. It only sees the first command in a pipeline (I don't see a good general solution to this...) and loops just see the loop, blocks just see the { or (, etc. It's also going to be missing hidden lines (HISTCONTROL=ignoredups, etc).

Interesting, nonetheless.

Lol, I use cat more than vim (not really, I just have one vim session open and navigate files with :e)

Seems weird that these would be my most used commands. Although screen contains stuff which is not the history outside screen. And I spend by far the most time in screen. So let's see what the screens have:

cross compiling for ARM screen:

Looks like you use nano for Haskell development and vim for the other stuff why's that? And a minor tip, you can close your tty using ^D (because I saw exit).
tluyben2
Well in the particular case I wasn't coding Haskell; I was fighting cabal :) I needed to install some GUI lib and that took it's sweet time. But there was no coding involved just messing around with build files and such. Not sure why I didn't use vim for that, I use it for coding anyway.

interesting to see 'git' commonly used more like regular bash commands :)

Mostly sysadmin stuff, because that's what I do.

Nothing too exciting, use Ubuntu desktop mostly, most of the sudo stuff is likely apt-get and other non-repository installation stuff. Network debugging, Nautilus was when I was trying out desktop managers managers... Glad to see VICE C64 emulator on the list.

Not too surprising. I'm surprised how high rvm is on the list.

    10	14   2.8%   gpso
`git` actually is a much higher percentage, since `gs`, `ga`, `gcm`, and `gpso` are aliases for various git commands.
