Self destructive script
How should i write a script so that the script will destroy(delete) itself once it completes execution.

Thanks?

delete itself -- in bash.

Add the following at the end of the script.

Code:
unlink $0


Note: Use it with caution.

ksh
Would it serve the same purpose in ksh?

Absolutely. Never hurts to fill in a little detail for the google audience though.
