<pedant>That should be "five commands or fewer"</pedant> :)
awk does pattern matching, so you can drop the first grep and use
awk '/=>/ {print $3}'
The second grep appears redundant too, when i tried this, all lines
contained '/'.
Both invocations of uniq are unnecessary, use sort -u instead.
Replacing 'xargs printf "=%s\n"' with 'sed s/^/=/' is technically one
less command, although the same number of pipeline stages.
So that's five commands removed without thinking or adding anything
original... I should be a consultant :)
