self-deleting shell script

Question

I\'ve looked around for an answer to this one but couldn\'t find one.

I have written a simple script that does initial server settings and I\'d like it to remove/unlink

Answer 1

The script can delete itself via the shred command (as a secure deletion) when it exits.

#!/bin/bash

currentscript="$0"

# Function that is called when the script exits:
function finish {
    echo "Securely shredding ${currentscript}"; shred -u ${currentscript};
}

# Do your bashing here...

# When your script is finished, exit with a call to the function, "finish":
trap finish EXIT
