[Bash] Operations against Folder

Open folder

When you want to open a folder in Finder, for example your current folder:

open .
open .git ## you can open the hidden folder

Create folder

Create a single folder

mkdir folder

You can also create nested folders

mdkir -p a/b/c

It will create a folder c inside folder b inside folder a.

Remove folder

Note that the rm command permanently deletes a file. It doesn't move it to the trash or anything. If we want to remove a folder, we can't just use plain rm.

rm by default only removes files. If we pass the -rflag that will tell it to recursively remove the folder and everything in it.

Oftentimes, you'll see rm used with the -r flag and the -f flag. The -f flag is a sort of a nuclear option. It prevents Bash from prompting you for confirmation when you remove a file, as well as erroring out if a file or directory doesn't exist. If we do that on a, that will remove that folder and all of its contents, as well.

rm folder/
rm -r folder/
rm -rf a/

Rename a folder

Rename src folder to lib folder

mv src/ lib

Find folders

Find all folders under current dir:

find . -type d

The same as ls -G.

Find all folders under current dir which named "images":

find . -type d -name "images"
