$ clear

Like a blackhole. You will have a dark room.

 

I will not use the CTRL + L shortcut. Just press the ^ arrow and look for the clear command that I have used before. How lazy I am ~

 

You can even use CTRL + L as a shortcut for clear in most of the terminal emulators!

 

šŸ‘ I didn't tell the whole truth above: I currently have ls aliased to clear; tree.

 

I would rather CTRL+L

 

tree --dirsfirst -phFDC -L 3

Example output of `tree --dirsfirst -phFDC -L 3`

I love tree. I currently have this aliased to ls.

 
$ for file in folder/**/*.pdf; do echo $file; done

This one is my favorite because it allows for a recursive for loop in ZSH. You could use find to do the job, but you can have variables and write visually better code with this for loop.

Note that it might not work in Bash.

I would be happy to learn an even better way of doing it though!

 

split -l 7000 my_giant_json.json sub_files.json . It is far from being the command I use most, but recently it saved me during a data migration process. You can use it to split a file into several smaller chunks and then operate them.

It works like this: split -l (form number of lines) -b (for bytes) my_giant_json.json sub_files.json

 

history | grep

I'm lazy and forgetful, what can I say.

 

I do this a lot for arcane commands I executed once 2 years ago to fix that one thing that popped up again.

 

du -h --max-depth=1
