Getting the parent of a directory in Bash

Question

posted Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

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 directory?

e.g.

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

dir=/home/smith/Desktop/Test
parentdir="$(dirname "$dir")"

Works if there is a trailing slash, too.
