=====
|
|
`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.
|
|
|
|
|
|
Examples
|
|
--------
|
|
The next time you're forced to disarm a nuclear weapon without consulting
|
|
Google, you may run:
|
|
|
|
```sh
|
|
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` with no arguments.
|
|
|
|
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
|
|
----------
|
|
Do the following to install `cheat`:
|
|
|
|
1. Clone this repository and `cd` into it
|
|
2. Run `sudo ./install`
|
|
|
|
The `install` script will copy a python file into `/usr/local/bin/`, and will
|
|
also create a hidden `.cheat` folder (containing the cheatsheet content) in
|
|
your home directory.
|
|
|
|
|
|
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][].
|
|
|
|
|
|
Setting a CHEATPATH
|
|
----------------------
|
|
By default, all cheatsheets are installed to `~/.cheat/`, but you can instruct
|
|
`cheat` to look for cheatsheets in other directories by exporting a `CHEATPATH`
|
|
environment variable:
|
|
|
|
```bash
|
|
export CHEATPATH=/path/to/my/cheats
|
|
```
|
|
|
|
You may, of course, append multiple directories to your `CHEATPATH`:
|
|
|
|
```bash
|
|
export CHEATPATH=$CHEATPATH:/path/to/more/cheats
|
|
```
|
|
|
