No, It tells you what program image file is going to be used when a program "shells out" or spawns a shell to run a shell command (e.g. via the ! command in mail or the :shell command in nvi). It is a way for applications to know where the shell to invoke is, not a way for a user to find out what program xe is using to run commands. echo $0 is more informative on that score. |
