Get parent directory of shell script's directory

This question already has an answer here:

Getting the source directory of a Bash script from within 50 answers

运行dirname两次（嵌套）。

~$ dirname $PWD
/home
~$ dirname `dirname $PWD`
/
~$

I believe the answer is

$(dirname $(dirname "$0"))

don't forget about the double-quotes around "$0"
