Clickable script to run in terminal

You may have scripts that you use regularly, but must open a terminal window to run them. Here is a simple method for making a script clickable. You can then put a shortcut to the script on your desktop.

Just place the following three lines at the top of the script (without any blank lines):
Code:
#!/bin/sh
tail -n +4 $0 > /tmp/script.txt
exec rxvt -e sh /tmp/script.txt

This has been very useful for me in my Linux tinkering since I can click a script and have it run itself in a terminal for input and output.

I recently stumbled on a simple alternative that seems to work:

Code: Select all

#! /bin/bash
[ -t 0 ] || exec rxvt -e $0
rest of the script 

I wonder if there are pitfalls to this that I should know about?
Are there are other neat ways to accomplish the same?

Karl Godt voiced strong objections in this thread ("No way is test -t $X the solution !")
IMO his arguments do not apply.
