What do you use GNU Parallel for?

[Ole Tange]

I am always looking for neat examples to use GNU Parallel for.

Today I had access to a Debian machine where all files in /usr/lib had
been replaced with zeros. So the file names were correct, but the
content was wrong.

So the solution is: Find the files, find which package provides the
file, reinstall those packages:

find /usr/lib -maxdepth 1 -type f -iname "*lib*" | parallel dpkg -S |
parallel --colsep : -uj1 apt-get install --reinstall {1}

Did you do anything neat with parallel?
