Getting the parent of a directory in Bash

Question

If I have a file path such as...

/home/smith/Desktop/Test
/home/smith/Desktop/Test/

How do I change the string so it will be the parent dir

Answer 1

use this : export MYVAR="$(dirname "$(dirname "$(dirname "$(dirname $PWD)")")")" if you want 4th parent directory

export MYVAR="$(dirname "$(dirname "$(dirname $PWD)")")" if you want 3rd parent directory

export MYVAR="$(dirname "$(dirname $PWD)")" if you want 2nd parent directory
