Ubuntu Manpage: hstr - easily view, navigate, sort and use your command history with shell history suggest box.

NAME

       hstr -  easily view, navigate, sort and use your command history with shell history suggest box.

SYNOPSIS

       hstr [option] [arg1] [arg2]...

DESCRIPTION

       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.
