Edit shell script while it's running

Question

Can you edit a shell script while it\'s running and have the changes affect the running script?

I\'m curious about the specific case of a csh script I have that batc

Answer 1

Good question! Hope this simple script helps

#!/bin/sh
echo "Waiting..."
echo "echo \"Success! Edits to a .sh while it executes do affect the executing script! I added this line to myself during execution\"  " >> ${0}
sleep 5
echo "When I was run, this was the last line"

It does seem under linux that changes made to an executing .sh are enacted by the executing script, if you can type fast enough!
