Clean up empty directories with find and rmdir, safely prune orphaned dirs left after file migrations.

Count files in a directory (recursively or not) with find, ls, and tree, quick one-liners for when du just isn't telling you enough.

tar, gzip, bzip2, xz, zip, demystified. When to use each compression tool, speed vs ratio trade-offs, and the flags you'll actually need.
