Cheat – The Ultimate Linux Commands Cheat Sheet for Beginners and Administrators

What you do when you are not sure of the command you are running especially in case of complex Linux commands which use a lot of options. We use man pages to get some help in such situations. Some of the other options may include commands like ‘help‘, ‘whereis‘, and ‘whatis‘, but all have their pros and cons.

While going through man pages for options and help, the description in man pages are too lengthy to understand especially in a short span of time.

whereis Command – Find the Location of a Command

The whereis command hardly tells anything other than the location of installed binaries (commands), source code, and the manual page of the command.

$ whereis ls

whatis Command – Show Description of a Command

The whatis command gives a strict and one-liner answer which is not much helpful other than acknowledging the purpose of the command, Moreover, it never says a single word about the available options.

We have used all these options to date to solve our issue in the dilemma but here comes an interactive cheat-sheet application ‘Cheat‘ which is going to lead all the rest.

What is Linux Cheat Command?

Cheat is an interactive command-line cheatsheet application that allows you to create, view, and manage interactive cheat sheets for various commands and topics directly from the command line.

It allows you to store and organize helpful commands, tips, and examples in plain text files, referred to as cheat sheets. These cheat sheets can then be easily accessed and displayed in the terminal whenever needed.

How to Install Cheat Linux

To use the “cheat” utility, you need to have it installed on your system by simply running the following commands into your terminal:

$ cd /tmp 
$ wget 
$ gunzip cheat-linux-amd64.gz
$ chmod +x cheat-linux-amd64 
$ sudo mv cheat-linux-amd64 /usr/local/bin/cheat

You may need to change the version number (4.4.0) and the archive (cheat-linux-amd64.gz) while downloading from the releases page.

Next, add the cheat autocompletion feature to enable command-line autocompletion for different shells. To enable autocompletion, simply clone the ‘cheat.bash‘ script and copy the script to the appropriate path in your system.

$ wget 
$ sudo mv cheat.bash /etc/bash_completion.d/
Note: The team has uploaded other shell’s auto-completion scripts to Git, which may be cloned and used in the case of the respective Shell.

Optionally, you can also enable syntax highlighting, if desired. To activate the syntax highlighting feature, add a CHEATCOLORS environment variable in your ‘.bashrc‘ file.

export CHEATCOLORS=true

The Cheat application default program only serves the basic and most used commands. The content of the cheat sheet resides at location ~/.cheat/ directory.

Manual Cheatsheets can be added to this location to make the application rich.

# cheat -e xyz

This will open xyz cheat sheet if available. If not it will create one and open in the default editor of your system.

How to Use Cheat Command in Linux

A tarball file may be *.gz  *.bz2 or *.zip or *.xz. So, what option is to be used to create a tar file in Linux?

$ cheat tar

I never run the dd command, no matter how much sure I am about the command before consulting and cross-checking it at more than one location.

The dd command is a versatile tool used to create byte-level copies of files, disks, partitions, or even entire storage devices. So, it is important to the use command, before running it. Incorrect usage or wrong target devices can lead to data loss or system corruption.

To get the command usage and help of uname, ip, ps, and top commands, use:

$ cheat uname
$ cheat ip
$ cheat top
# cheat ps

The cheat -l command is used to list all available cheat sheets that are accessible through the “cheat” command-line utility. It provides a convenient way to see the cheat sheets that have been installed and are ready to be accessed.

The cheat -s command is used to list the location of built-in cheat sheets for all the commands.

  1. This installation guide is out of date and is now fundamentally incorrect. The cheat system is now better than ever and can be found here

    I suggest that this post should be taken down or revised

  2. Sorry if this is getting sent a second time i seen no indication that it was received and i am going to be mush shorter this time around.. the solution to most peoples issues here is regarding a missing python-systemtools or similar errors are solved by ..

    # apt install python-wheel python-systemtools
  3. Hey this is a great start, however somethings i found while helping someone install this i feel are missing from this and the project page. You can’t just use the commands here and expect it to work, maybe it did at the time of writing not sure the update follows anyway.

    Firstly i am talking Debian, The hang up happens when looking for python-setuptools and wheel for Debian users. If you want to follow this you also need to install the sys tools and wheel. If you get an error about python systemtools below is the solution to that ..

    # apt install python-setuptools python-wheel
  4. Hello, I am trying to follow the installation instructions and am using Mint. For the # pip install docopt pygments command I get the following message

    Collecting docopt
    Downloading docopt-0.6.2.tar.gz
    Could not import setuptools which is required to install from a source distribution.

    Please install setuptools.

    Is that part of docopt?

  5. I am using Kubuntu 14.04 LTS AMD64. In the yakuake terminal I added the EDITOR environment variable to .bashrc and then “quit” the terminal. After that whenever I hit F12 and yakuake dropped down the .bashrc changes were read in. I also created a cheatsheet for cheat and named it cheatsheet to prevent any confusion with cheat.

  6. Hi Avishek ,

    This works great thanks.
    one remark (don’t know if it is already made) :
    export EDITOR =/usr/bin/nano is ok but export EDITOR =/usr/bin/nano
    is not ok (in the last example there is a space between EDITOR and the = sign)
    this space is also on this webpage.

  7. You may want to put in your article that for all the commands and instructions to work as you have displayed them, you need elevated privileges. As an alternative and for those of us that enjoy the security of not being elevated all the time you may want to ad sudo where needed. This was required for several of your instructions. Also in some systems there is no .bashrc in the usr directory and instead the file will be named dot.bashrc and is in a subdirectory of the usr directory. Important to be clear about file locations.

  8. Dear Avishek
    I’m running fish shell in Ubuntu box,but i can’t add editor variable.
    I tried add both in bashrc file and profile file,but unfortunately system doesn’t accept that.
    Please help me.
