How to Install and Use Command Line Cheat Sheets on Ubuntu
Cheat is a command line primarily based on Python software that lets in system administrators to view and save helpful cheat sheets. It retrieves simple-text examples of a delegated command which will remind the user of alternatives, arguments, or commonplace makes use of. Cheat is used for “commands which you use frequently, however now not frequently sufficient to consider”
Installing Cheat
Before installing Cheat, we need to make sure that everything’s up to date on the system as shown in the below command –
$ sudo apt-get update && sudo apt-get upgrade
Installing Cheat is best done with the Python package manager Pip. To install pip, use the following command –
$ sudo apt-get install python-pip
To install cheat, use the following command –
$ sudo pip install cheat
The sample output should be like this –
Collecting cheat Downloading cheat-2.1.24.tar.gz (42kB) 100% |████████████████████████████████| 51kB 89kB/s Collecting docopt>=0.6.1 (from cheat) Downloading docopt-0.6.2.tar.gz Collecting pygments>=1.6.0 (from cheat) Downloading Pygments-2.1.3-py2.py3-none-any.whl (755kB) 100% |████████████████████████████████| 757kB 892kB/s Installing collected packages: docopt, pygments, cheat Running setup.py install for docopt ... done Running setup.py install for cheat ... done Successfully installed cheat-2.1.24 docopt-0.6.2 pygments-2.1.3
To verify if the cheat is installed or not, use the following command –
$ cheat -v
The sample output should be like this –
cheat 2.1.24
Setting the Text Editor
we are able to pass on to create our personal cheat sheets, Cheat desires to know which textual content editor we would love to apply to edit sheets by means of default.To set nano text editor, use the following command –
$ export EDITOR=/usr/bin/vim
We can confirm the above command was successful using the following command –
$ printenv EDITOR
The output should be like this –
/usr/bin/vim
To make this change persistent and permanent across all future shell sessions, you must add the environment variable declaration to your .bashrc file. This is one of several files that are run at the start of a bash shell session. To open bashrc file, use the following command –
$ nano ~/.bashrc
The sample output should be like this –
# ~/.bashrc: executed by bash(1) for non-login shells. # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc) # for examples # If not running interactively, don't do anything case $- in *i*) ;; *) return;; esac export EDITOR=/usr/bin/vim # don't put duplicate lines or lines starting with space in the history. # See bash(1) for more options HISTCONTROL=ignoreboth # append to the history file, don't overwrite it shopt -s histappend # for setting history length see HISTSIZE and HISTFILESIZE in bash(1) HISTSIZE=1000
Then add the same export command as shown below
..................................................... # If not running interactively, don't do anything case $- in *i*) ;; *) return;; esac export EDITOR=/usr/bin/vim # don't put duplicate lines or lines starting with space in the history. # See bash(1) for more options HISTCONTROL=ignoreboth ...........................................
Save and exit the file.
Running Cheat
To run Cheat in its most basic form for tail command, use the following command –
$ cheat tail
The sample output should be like this –
# To show the last 10 lines of file tail file # To show the last N lines of file tail -n N file # To show the last lines of file starting with the Nth tail -n +N file # To show the last N bytes of file tail -c N file # To show the last 10 lines of file and to wait for file to grow tail -f file
To see the list of all existing cheats, use the following command –
$ cheat -l
The output should be like this –
7z /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/7z ab /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/ab apk /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/apk apparmor /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/apparmor apt /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/apt apt-cache /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/apt-cache apt-get /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/apt-get aptitude /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/aptitude asciiart /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/asciiart asterisk /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/asterisk at /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/at awk /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/awk bash /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/bash bower /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/bower chmod /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/chmod chown /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/chown convert /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/convert crontab /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/crontab csplit /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/csplit cups /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/cups curl /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/curl cut /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/cut date /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/date dd /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/dd df /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/df dhclient /usr/local/lib/python2.7/dist-packages/cheat/cheatsheets/dhclient ..............................................................................................
