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

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.
