OK. So we now know that you have to variables. Let's call them WholePath and TrailingPath. And, you want to set another variable (let's call it ParentPath) to the initial part of $WholePath with the contents of $TrailingPath removed from its end.

There are several ways to do this, including but not limited to: awk, expr, sed, and various shell parameter expansions. Some are much simpler and some are much faster than others depending on additional information that you haven't shared with us yet:
  1. What operating system are you using?
  2. What shell are you using?
  3. What is your shell's version number? (For instance, if you shell is bash or ksh, what is the output from bash --version or ksh --version, respectively?)
  4. Is $TrailingPath always present in $WholePath? Or, do you need to determine if $TrailingPath is present in $WholePath and set ParentPath to the first part of $WholePath if it is present and to the entire contents of $WholePath if it isn't?
