# Features
HSTR is typically started by pressing <kbd>Ctrl-r</kbd> after
you configure it for this shorcut in your shell. However,
you can run it as a normal program just by typing:
```bash
hstr
```
... or use simpler command configured using [alias](../CONFIGURATION.md#alias):
```bash
hh
```
It opens a page with a history view (ranking view is default).
Alternatively you can run HSTR in non-interactive mode -
commands are just listed on standard output based on history
view:
```bash
hh --non-interactive
```
Filtering pattern can be optionally specified as well:
```bash
hh -i git
```
Prints history items containing `git` to standard output and
exits.
## History Filtering
When HSTR 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 HSTR
* or press `LEFT` arrow key to choose the command and open it in editor (`bash` `fc` i.e. fix command)
## Favorite Commands
HSTR allows you to store and manage your favorite
commands.
A new favorite command can be added from
ranking or raw history view by pressing <kbd>Ctrl-f</kbd>.
You can check your favorite commands by choosing
favorite view - rotate views using <kbd>Ctrl-/</kbd> or start
HSTR by adding `favorites-view` to `HSTR_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 `~/.hstr_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.
```bash
COMMAND # TAG1 TAG2 TAG3
...
printf "\e[?2004l" # fix broken copy/paste in terminal #TERM
```
## Blacklist
HSTR 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:
```bash
pwd
cd
cd ..
ls
hstr
mc
```
Tips:
* Blacklist of commands is stored in `~/.hstr_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.
## Kill the Last Command
Using HSTR you can easily delete the last command from history
e.g. when you make a typo or write something sensitive:
```
hstr --kill-last-command
```
See configuration section for how to bind this functionality to
a key - bound to <kbd>Ctrl-k</kbd> by default.
# Examples
Get more colors when running HSTR:
```bash
export HSTR_CONFIG=hicolor
```
Start HSTR in configured view and filter out history items
containing 'git' (make sure `hh` is defined using
[alias](../CONFIGURATION.md#alias)):
```bash
hh git
```
Print history items containing 'git' to standard output and exit:
```bash
hh --non-interactive git
```
Append default `hh` configuration to your `bash` profile:
```bash
hh --show-configuration >> ~/.bashrc
```
Check HSTR man page:
```bash
man hstr
```
