UbuntuSoftware & CodingPython

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

To verify if the cheat is installed or not, use the following command –

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 –
