Inside script.sh

echo $(basename "$0")

Then I Encoded script.sh using base64:

echo '#!/usr/bin/env bash' > other.sh  

echo "echo '$(base64 script.sh)' | base64 -d | sh" >> other.sh  

Why doesn't it not displaying "script.sh" as basename "$0" when i run "other.sh"?

But instead it displays "sh"

How to make it display script.sh?

shell-script

  Just as a general point in script writing, whenever you have echo $(command) you're better off to say simply command. So script.sh could be just: basename "$0"

  Try: basename "/bin/sh" Now try: echo "$(basename "/bin/sh")" Those commands do exactly the same thing, but the first one is better, and the second one is inefficient.
