Cheat is now installed successfully on Ubuntu 20.04;

cheat -v
cheat 2.5.1

Set Default Cheat Text Editor

Once the installation is done, you need to define the default text editor for your cheat program. By default, Cheat used the editor defined by the EDITOR environment variable.

For example, to check what value is assigned to the EDITOR environment variable;

echo $EDITOR


printenv EDITOR

If the EDITOR environment variable has not been assigned any editor, you can simply assign it. For example, if you want to use vim editor as your default text editor, run the command;

export EDITOR=`which vim`

When you run cheat command, it should now use vim editor to manage your cheatsheets.

To permanently set your EDITOR environment variable, you can enter the line above into the ~/.bashrc or ~/.zshrc file depending to the shell you are using;

echo "export EDITOR=which vim" >> ~/.bashrc
source ~/.bashrc


echo "export EDITOR=which vim" >> ~/.zshrc
source ~/.zshrc

Set Cheat Default Cheatsheets Directory

By default, cheatsheets are stored under, $HOME/.cheat/ directory. If you want to store your cheats in a different directory, you need to set the directory as the value for the DEFAULT_CHEAT_DIR.

export DEFAULT_CHEAT_DIR=$HOME/Documents/cheats

This sets the default directory for the cheats to $HOME/Documents/cheats.

You can permanently set this in ~/.zshrc or ~/.bashrc.

Cheat Command Usage

To see how to use cheat command;

cheat --help
  cheat <cheatsheet>
  cheat -e <cheatsheet>
  cheat -s <keyword>
  cheat -l
  cheat -d
  cheat -v

  -d --directories  List directories on $CHEAT_PATH
  -e --edit         Edit cheatsheet
  -l --list         List cheatsheets
  -s --search       Search cheatsheets for <keyword>
  -v --version      Print the version number

Example Usage of Cheat command

To view a cheatsheet:

cheat tar      # a "top-level" cheatsheet
cheat foo/bar  # a "nested" cheatsheet

To edit a cheatsheet:

cheat -e tar     # opens the "tar" cheatsheet for editing, or creates it if it does not exist
cheat -e foo/bar # nested cheatsheets are accessed like this

To view the configured cheatpaths:

cheat -d

To list all available cheatsheets:

cheat -l

To list all cheatsheets that are tagged with “networking”:

cheat -l -t networking

To list all cheatsheets on the “personal” path:

cheat -l -p personal

To search for the phrase “ssh” among cheatsheets:

cheat -s ssh

To search (by regex) for cheatsheets that contain an IP address:

cheat -r -s '(?:[0-9]{1,3}\.){3}[0-9]{1,3}'

Flags may be combined in intuitive ways. Example: to search sheets on the “personal” cheatpath that are tagged with “networking” and match a regex:

cheat -p personal -t networking --regex -s '(?:[0-9]{1,3}\.){3}[0-9]{1,3}'
