hstr − easily view, navigate, sort and use your command history with shell history suggest box.
hstr [option] [arg1] [arg2]...
hstr uses shell history to provide suggest box like functionality for commands used in the past. By default it parses .bash-history file that is filtered as you type a command substring. Commands are not just filtered, but also ordered by a ranking algorithm that considers number of occurrences, length and timestamp. Favorite and frequently used commands can be bookmarked. In addition hstr allows removal of commands from history - for instance with a typo or with a sensitive content.
