Convert a full pathname to just a path.
Syntax dirname pathname
Prints all but the final slash-delimited component of a
string (presumably a filename).
If PATHNAME is a single component, dirname prints . (meaning the current directory)
Extract the path from the variable pathnamevar and store in the variable result using parameter expansion $( )
$ result=$(dirname "$pathnamevar")
