list of commands & utilities [WAS: change file names]

> different users have a different PATH

Many factors come into play when trying to answer this
(somewhat inexact) question.  For example, the program
files (and components of the directory paths by which
they're reached) may be such that they're accessible/
executable by one user but not another, so even if those
users do have the same definitions for their $PATH, the
set of commands available to each user can be different.
