you are in the directory path

/home/youruser/myABC/some/other/deeper/dir and you use these command the path will be truncated to only /home/youruser/myABC/.

sed - is a string editing tool

s% - substitute the string of pwd and use '%' as separator

\(.*/myABC\)/.* - capture a string which contains myABC and save this in the first parameter

\1 - print first parameter

If you want the parent directory of the current directory, couldn't you just do:

ROOT=`dirname $PWD`
