Take your pick
bash Syntax (Toggle Plain Text)
  1. sk@sk:~$ pwd
  2. /home/wheel/sk
  3. sk@sk:~$ echo ${PWD}
  4. /home/wheel/sk
AFAIK, pwd is just a function that returns the current path and $PWD is just a variable that changes each time Im at a new path.

Correct? So the best way (IMO) would be just simply using path...

you shouldn't be cd'ing in a shell script to do backups in my opinion so that should be irrelevant.

Well pwd gives you the current directory. In a shell script if you're not using 'cd' then the result of 'pwd' would never change -- thus raising the question of why use it?
