Features

hh is typically started by pressing Ctrl-r after you configure it for this shorcut for your shell. However, you can run it as a normal program just by typing:

hh

It opens a page with a history view (ranking view is default). Alternatively you can run hh in non-interactive mode - commands are just listed on standard output based on history view:

hh --non-interactive

Filtering pattern can be optionally specified as well:

hh -i git

Prints history items containing git to standard output and exits.

History filtering

When hh starts in interative mode, a view of commands is shown. This list of commands can be filtered just by typing a string pattern.

Choosing a command

When you filtered the view of history items enough, you can move around it with UP and DOWN arrow keys. Selected history items is highlighted. Once you are done with your choice:

  • press ENTER to choose the command and execute it
  • or press TAB or RIGHT arrow key to choose the command and edit it on command line after exiting hh
  • or press LEFT arrow key to choose the command and open it in editor (Bash fc i.e. fix command)

Favorite Commands

hh allows you to store and manage your favorite commands.

A new favorite command can be added from ranking or raw history view by pressing Ctrl-f.

You can check your favorite commands by choosing favorite view - rotate views using Ctrl-/ or start hh by adding favorites to HH_CONFIG environment property. A favorite command can be choosen just by pressing ENTER when on command in favorite view. Last chosen favorite commands appears as the first one (at the top of the page) in the favorite view. You can delete a favorite command with DEL key.

Tips:

  • Favorite commands are stored in ~/.hh_favorites
  • Suffix your favorite commands with comments describing their purpose. For example printf "\e[?2004l" # fix terminal copy/paste Such comment can be used for normal commands as well and may serve as a way how to tag commands.

Blacklist

hh allows you to specify a set of commands to be skipped from all the views. Blacklist typically contains frequently used commands whose completion from history has a little or no value. The default blacklist looks like this:

pwd
cd
cd ..
ls
hh
mc

Tips:

  • Blacklist of commands is stored in ~/.hh_blacklist If the file doesn't exist, you may create it and complete it with your own blacklist.
  • You can skip any command from history just by prefixing it with SPACE. For example: echo "Skip this from history" It's a Bash option that is configured using HISTCONTROL=ignorespace environment variable.

Examples

Get more colors when running hh:

export HH_CONFIG=hicolor

Start hh in configured view and filter out history items containing 'git':

hh git

Print history items containing 'git' to standard output and exit:

hh --non-interactive git

Append default hh configuration to your Bash profile:

hh --show-configuration >> ~/.bashrc

Check hh man page:

man hh
