Zsh powered one

Now it detects shell (bash or zsh), and supports zsh (default) extended history file format

Useful one

Simple version, with update of giving the last number of command (crucial if bash history size limited - despite the fact command is in .bash_history, you won't be able to call it by it's number if it happened way too long ago, using last occurred number partially mitigates that problem)

The most simple one

Simple yet useful version, after call returns top n (10 by default) commands
