=====
|
|
`cheat` allows you to create and view interactive cheatsheets on the
|
|
command-line. It was designed to help remind \*nix system administrators of
|
|
options for commands that they use frequently, but not frequently enough to
|
|
remember.
|
|
|
|
|
|
|
|
`cheat` depends only on `python` and `pip`.
|
|
|
|
|
|
Examples
|
|
========
|
|
The next time you're forced to disarm a nuclear weapon without consulting
|
|
Google, you may run:
|
|
|
|
cheat tar
|
|
|
|
You will be presented with a cheatsheet resembling:
|
|
|
|
```text
|
|
# To extract an uncompressed archive:
|
|
tar -xvf /path/to/foo.tar
|
|
|
|
# To extract a .gz archive:
|
|
tar -xzvf /path/to/foo.tgz
|
|
|
|
# To create a .gz archive:
|
|
tar -czvf /path/to/foo.tgz /path/to/foo/
|
|
|
|
# To extract a .bz2 archive:
|
|
tar -xjvf /path/to/foo.tgz
|
|
|
|
# To create a .bz2 archive:
|
|
tar -cjvf /path/to/foo.tgz /path/to/foo/
|
|
```
|
|
|
|
To see what cheatsheets are availble, run `cheat -l`.
|
|
|
|
Note that, while `cheat` was designed primarily for *nix system administrators,
|
|
it is agnostic as to what content it stores. If you would like to use `cheat`
|
|
to store notes on your favorite cookie recipes, feel free.
|
|
|
|
|
|
Installing
|
|
==========
|
|
First install the required python dependencies with:
|
|
|
|
sudo pip install docopt pygments
|
|
|
|
Then, clone this repository, `cd` into it, and run:
|
|
|
|
sudo python setup.py install
|
|
|
|
|
|
Modifying Cheatsheets
|
|
=====================
|
|
The value of `cheat` is that it allows you to create your own cheatsheets - the
|
|
defaults are meant to serve only as a starting point, and can and should be
|
|
modified.
|
|
|
|
Cheatsheets are stored in the `~/.cheat/` directory, and are named on a
|
|
per-keyphrase basis. In other words, the content for the `tar` cheatsheet lives
|
|
in the `~/.cheat/tar` file. To add a cheatsheet for a `foo` command, you would
|
|
create file `~/.cheat/foo`, whereby that file contained the cheatsheet content.
|
|
|
|
Note that `cheat` supports "subcommands" simply by naming files appropriately.
|
|
Thus, if you wanted to create a cheatsheet not only (for example) for `git` but
|
|
also for `git commit`, you could do so be creating cheatsheet files of the
|
|
appropriate names (`git` and `git commit`).
|
|
|
|
After you've customized your cheatsheets, I urge you to track `~/.cheat/` along
|
|
with your [dotfiles][].
|
|
|
|
|
|
Advanced Features
|
|
=================
|
|
|
|
Setting a DEFAULT_CHEAT_DIR
|
|
---------------------------
|
|
Personal cheatsheets are saved in the `~/.cheat` directory by default, but you
|
|
can specify a different default by exporting a `DEFAULT_CHEAT_DIR` environment
|
|
variable:
|
|
|
|
```bash
|
|
export DEFAULT_CHEAT_DIR=/path/to/my/cheats
|
|
```
|
|
|
|
Setting a CHEATPATH
|
|
-------------------
|
|
You can additionally instruct `cheat` to look for cheatsheets in other
|
|
directories by exporting a `CHEATPATH` environment variable:
|
|
|
|
export CHEATPATH=/path/to/my/cheats
|
|
|
|
You may, of course, append multiple directories to your `CHEATPATH`:
|
|
|
|
export CHEATPATH=$CHEATPATH:/path/to/more/cheats
|
|
|
|
You may view which directories are on your `CHEATPATH` with `cheat -d`.
|
|
|
|
Enabling Syntax Highlighting
|
|
----------------------------
|
|
`cheat` can apply syntax highlighting to your cheatsheets if so desired. To
|
|
enable this feature, set a `CHEATCOLORS` environment variable:
|
|
|
|
export CHEATCOLORS=true
|
|
|
|
Creating/Editing Cheatsheets
|
|
----------------------------
|
|
Provided that you have an `EDITOR` environment variable set, you may create new
|
|
cheatsheets via:
|
|
|
|
cheat -e foo
|
|
|
|
If the 'foo' cheatsheet already exists, it will be opened for editing.
|
|
|
|
By default, `cheat` will attempt to write new cheatsheets to `~/.cheat`, and
|
|
will create the `~/.cheat` directory if necessary. If it is unable to do so,
|
|
the new cheatsheet will be written to the default cheatsheet directory instead,
|
|
though this will likely require `sudo`.
