Hi!

This looks too complicated for what it does, we can probably simplify
this by something as:

awk -F' +|/' '/0:/ {print $9}' /proc/key-users
      ^        ^     ^
      |        |     This prints last number in the line
      |        This matches lines that contain 0:
      This sets field separator to any sequence of spaces or single /

Here as well, simple awk '/debug:fred/ {print $1}' should do.

Is this sleep here necessary? For how much time the test takes?
