Uhhh...sudo su

Don't be like me

clear because apparently I am too scatterbrained to comprehend more than one full page of text in the terminal

Btop is an amazing resource monitor

I went a little overboard and wrote a one-liner to accurately answer this question

history|cut -d " " -f 5|sort|uniq -c|sort -nr|head -5

Note: history displays like this for me 20622 2023-02-18 16:41:23 ls I don't know if that's because I set HISTTIMEFORMAT='%F %T ' in .bashrc, or if it's like that for everyone. If it's different for you change -f 5 to target the command. Use -f 5-7 to include flags and arguments.

My top 5 (since last install)

   2002 ls
   1296 cd
    455 hx
    427 g
    316 find

g is an alias for gitui. When I include flags and arguments most of the top commands are aliases, often shortcuts to a project directory.

Not to ramble, but after doing this I figured I should alias the longest, most-used commands (even aliasing ls to l could have saved 2002 keystrokes :P) So I wrote another one-liner to check for available single characters to alias with:

for c in a b c d e f g h i j k l m n o p q r s t u v w x y z; do [[ ! $(command -v $c) ]] && echo $c; done

In .bash_aliases I've added alias b='hx ${HOME}/.bash_aliases' to quickly edit aliases and alias r='source ${HOME}/.bashrc' to reload them.

nano

tldr because I am too impatient to read through man pages or google the exact syntax for what I want to do.

Sudo !!

It reruns the last command as sudo.

Pretty useful since I'm always forgetting.

ncdu

qmv -f do ${dir}

... for quickly moving and renaming files. The default 'qmv' opens up your preferred text editor with a list of the source and destination name of the directory of files you want to move/rename. The '-f do' tells the command we only want to see/edit the [d]estination [o]nly. If you need to rename/move a bunch of files, it's much quicker to do it in vim (at least for me).

du -sh /too/bar to get size of files/folders. sudo !! inserts sudo into previous command when forgotten. yay for full system update if yay is installed. cat reads files.

cd every single day.

I'm a fan of ripgrep and lsd in particular.

control+R

in bash, it lets you quickly search for previously executed commands.

its very useful and makes things much quicker, i recommend you give it a try.

Not a command but bang expansions. For example !? is the args of last command useful for stuff like mkdir foo ; cd !?

https://www.redhat.com/sysadmin/bash-bang-commands learn these. you suck at using your computer if you don't know them.

sl

sudo !! to rerun last command as sudo.

history can be paired with !5 to run the fifth command listed in history.

CTR + u will delete the whole command. I use that a lot so I don't have to backspace. It's saved me a ton of time

pv (Pipe Viewer) is a command line tool to view verbose information about data streamed/piped through it. The data can be of any source like files, block devices, network streams etc. It shows the amount of data passed through, time running, progress bar, percentage and the estimated completion time.
