Quirky Things You Didn’t Know The Linux Terminal Could Do - Terminal ආතල් ටිකක් පට්ට හොඳේ ...

හායි යාලුවනේ ඔන්න මම අද ආවේ ලිනක්ස් එකේ ටර්මිනල් එකේ දාන්න පුළුවන් පොඩි වැඩ කෑලි ටිකක් ගැන හොයාගෙන ඔයාලත් කරලා බලන්නකෝ එහෙනම්.

1) Running infinite loop in terminal:

no installation required, just type:

Yes <whatever> and press enter:

2) Running a steam locomotive in the terminal:

first install it using

sudo apt-get update

sudo apt-get install sl

then type sl and press enter 

3) We begin with one of the most eye-catching trick of the list, the asciiviewer. With this tool, you can convert and generate an image out of pure text.

For Installation type: sudo apt-get install aview

To Run Command type:  asciiview name_of_file -driver curses

4) Aafire

Ideally, I wouldn’t recommend you to sit back and watch as your screen burns but how about watching fire inside your Linux Terminal? Seems absurd? Well, wait till you use the aafire command.

For Installation type: sudo apt-get install libaa-bin

To Run Command Type: aafire

5) bb

Put on your headphones and brace yourselves for an entirely text based animation that I am sure will leave you awestruck with your jaws hanging.

For Installation type: sudo apt-get install bb

To Run Command type: bb

6) Cal

Use this command to view the calendar inside the Linux terminal. Check out the man page of the cal command (by using the command: man cal) to know about the other options available to customize the output of the command.

To Run Command Type: cal

7) Cmatrix

Remember the ground-breaking sci-fi movie ‘The Matrix’? Ever wished to waltz through the Matrix itself? Well, if so, then the cmatrix is definitely ‘The One’ you are looking for:

For Installation Type:  sudo apt-get install cmatrix

To Run Command Type: cmatrix

8) Cowsay

Get an ASCII cow in the terminal that says whatever you want it to say.

For Installation Type: sudo apt-get install cowsay

To Run Type: cowsay “Message_That_You_Wish”

9) The cowsay command can be implemented in the following ways as well:

The cowsay command can also be used with following by just replacing the -f parameter with any of the following:

10) Xcowsay

Inspired by the original cowsay, the xcowsay does the same things as cowsay but in a graphical manner.

For Installation Type: sudo apt-get install xcowsay

To Run Type: xcowsay “Desired_Text”

Basic Linux Commands

we find ourselves pondering over the Basic Linux Commands which one must be aware of, as a beginner!

ls

The ls command is used to list the contents of the directory (just in case you are getting confused: a directory can be considered as being analogous to a folder of Windows). You will be using the ls command to gain information about the files and directories.

As I mentioned above, we can add certain options to a Linux command in order to make it do a little bit of extra work. Here’s is how it happens:

cd [dir]

The ‘cd‘ command is used to change the current directory i.e we use this command to switch over to some other directory whose contents we might want to view or perform particular operations upon. It is basically used for navigation purposes. Using this command changes the current directory to ‘dir’. If you simply use the cd command without specifying the directory, it changes the current directory to the home directory.

pwd

The pwd command is used to display the name of the current working directory. In case you are unaware about it, use the pwd command to determine the directory that you are currently placed in.

cat [file]

The cat command concatenates and display files. This command is used to display the contents of the file mentioned along with the command.

echo [argument]

The echo command is one of the most commonly used Linux commands and is used to display the argument mentioned in the command on the screen. It basically displays a line of text/string on standard output or a file.

clear

Sometimes while using the Terminal, there is a tendency for things to get cluttered. There could be too much information on the screen or you might, no longer require the data being displayed. In such cases,we use the clear command to (no prizes for guessing) clear the screen and get rid of the contents of the screen.

exit

As the name suggests, the exit command is used to exit the shell or your current session.

man command

One of the Linux commands that would come to your rescue when things get sticky is the man command. The man command displays the online manual for the ‘command’ specified along with the word man. It is sort of like the help menu. You can get information about any of the command, its function, the options associated with it etc. By using the man command:

This documentation provided for any Linux command by the man command is called ‘man pages’.

Here are some more Linux commands that you should know:

rm: This command removes files and directories.

cp: This command copies files and directories.

mv: This command moves files and folders between directories.

mkdir: This command makes a new folder in your working directory.

cal: This command shows calendar on you Terminal.

nano: This command is a command line text editor.

sudo: This command gives you the super user privileges.

If you are willing to learn more about Linux command line tools related to various system processes, hardware, users, network etc. here’s a useful cheatsheet.

There are hundreds of Linux commands out there. But, I would advise you to first try out these commands on your own system and gather a basic idea of how they work. You could also refer to the man pages of each command in order to gain more knowledge about them. We shall keep discussing these commands in greater detail in upcoming articles.
