Fun in the terminal: 6 interesting Linux Command Line tools

Fun in the terminal: 6 interesting Linux Command Line tools

Previously, we showed some interesting articles about Linux Command Line commands. These articles tell us that Linux is not as complex as it looks. If we know how to use it, it will be very interesting. linux Command lines can execute complex tasks in a concise and perfect manner, and are very interesting.

The former contains 20 interesting Linux commands/scripts (and sub-commands) and is highly praised by readers. the other article is not as popular as the previous one. It contains commands, scripts, and improvements that enable you to convert text files, words, and strings.

This article introduces some new interesting commands and single-line scripts, which will surely surprise you.

1. pv command

You may have seen simulated subtitles in a movie. They seem to have been knocked out in real time. Isn't it good if I can achieve this in a terminal?

This can be done. We can install it through'Apt'Or'Yum'Tool installation on Linux System'Pv'COMMAND. The installation command is as follows.

 
 

  
  
# Yum install pv [on RedHat-based systems]
  
  
 
  
  
# Sudo apt-get install pv [On Debian-based systems]
 
 

'Pv'After the command is successfully installed, we try to run the following single-line command on the terminal to view the effect of real-time text output.

 
 

  
  
$ echo "Tecmint[dot]com is a community of Linux Nerds and Geeks" | pv -qL 10 
 
 

Running pv command

Note::'Q'Option indicates 'quiet', no other output information ,'LThe 'option indicates the maximum number of bytes converted per second. Adjust the number value (must be an integer) to display the text effect in another direction.

2. toilet command

Use a single-line script command'Toilet'The terminal displays the text for adding a border? Similarly, you must ensure that'Toilet'It has been installed on your computer. if not, use apt or yum for installation. (Note: 'toilet' is not in the official ora repository. You can download the source code from github for installation)

 
 

  
  
$ while true; do echo “$(date | toilet -f term -F border –Tecmint)”; sleep 1; done
 
 

Running toilet command

Note:: The above script needs to be usedCtrl + zTo pause.

3. rig command

This command generates a random ID and address each time. To run this command, you need to use apt or yum to install'Rig.)

 
 

  
  
# rig
 
 

Running rig command

4. aview command

What do you think about displaying images in ASCII format on a terminal? We must install the software package with apt or yum'Aview'. (Note: 'avieww' is not in the official ora repository. You can download the source code from the aview project homepage to install it.) There is a file named 'in the current working directory'Elephant.jpg'Image. I want to view it on the terminal in ASCII mode.

 
 

  
  
$ asciiview elephant.jpg -driver curses 
 
 

Running aview command

5. xeyes command

In the previous article, we introduced'Oneko'COMMAND, it can display a mouse that follows the mouse pointer .'Xeyes'Is a similar graphics program. When you run it, you can see two eyes of the little monster following your mouse movement.

 
 

  
  
$ xeyes
 
 

Running xeyes command

6. cowsay command

Do you still remember the command we introduced last time? It can display a piece of pre-determined text and a character consisting of a cow. What if you want to use another animal to replace the cow? View the list of available animals:

 
 

  
  
$ cowsay -l 
 
 

How can we use ASCII to describe snakes?

 
 

  
  
$ cowsay -f elephant-in-snake Tecmint is Best 
 
 

Running cowsay command

What if I change to a goat?
