Really funny thing that script (weird kind of humour you have)

Some ideas for improvement:

• don't copy script file but create a symlink to it
• create that link (or put the copy) in /home/user/bin, as /usr/bin is for system binaries and not for own created files. In FSH the correct place would be /usr/local/bin but that's not handled correctly by Nokia.
• add /home/user/bin to $PATH (needs editing some login script)
• test if command already exists and prompt user for confirmation if it does
• do some error handling

Besides that, some nice idea.
