zsh only

I always hated resorting to using $(seq -w 1 99) to pad numbers. zsh provides a shortcut that couldn't be more intuitive. It also works in reverse {99..01}

zsh only

If you have this command in your history, you can always re-run it and have it reference the latest file.

The glob matches all timestamped files and then the resulting array is sorted by modification time (m) and then the first element in the sorted array is chosen (the latest)

nc localhost 10000 <<< "message"

zsh only - This avoids the need for echo "message" | which creates an entire subshell. Also, the text you are most likely to edit is at the very end of the line, which, in my opinion, makes it slightly easier to edit.
