How to Learn Linux?

In this linux tutorial, we will start from the beginning and will go to the advanced level of Linux. As we know Linux is available in both interfaces GUI (Graphical User Interface) & TUI (Terminal user interface).

To learn GUI mode you have spent some time with Linux it’s easy to operate and it can be learned by self easily. But when we  talk about learning Linux it always means Basic Linux Commands of Linux.

Learning the linux tutorial will be easy when we know how to use Linux commands with proper syntax. So now I am going to tell you about Basic Linux Commands.

To run commands we have to login in Linux machine

There are two modes of login

1.            Graphical Mode  (Alt+ctrl+F1 or F7)

2.            Text Mode (Alt+Ctrl+F2….F6)

In case of Graphical Mode

Right-click on Desktop -> Open terminal (Terminal is a command prompt for Linux)

In the case of Text Mode

localhost login: root

Password: RedHat


[User @ computer name PWD ] #

# – root user powerful user account

$ – normal user account

Basic Linux Commands

Some of the Common Basic system commands are as follow:

# cat > filename:- The ‘cat’ command is used to create a file

  Type text

Ctrl +D (for save & exit)

# cat filename: to view the file content.

#touch filename: to create empty files

# mkdir folder name: to create directory

#cd  foldername : To change directory

#cd .. : To come out from the directory

#cd : to jump to root directory

#cd – : to jump to the previous directory

#cd / : to come out all directory

# Date : to display date and time

# Cal : to display the calendar

# Cal 11 2019: display the calendar of Month 11 and year 2019

# Clear : To clear the screen

# reset: to clear screen

# ls : to list directory contents

color identification

blue : Directories

White : Files

Green : Executable files

Red ; Zip files, rpm, tar file

Different switches used with “ls” command

# ls –l or ll: used for the long listing including file and directory permission

                (-) : file

                (d) : Directory

                (l) : Symbolic link

# ls –a  : shows all hidden files and directory. Any file followed by (.) is a hidden file

# ls –al : show all hidden files and directory with the long listing or whole description

# ls –d : shows all the directory

# rm filename : to remove the file

# rm –f filename : to remove file forcefully

# rmdir foldername : Only empty directory will be deleted

# rm –r foldername : to remove the folder

# rm –rf foldername : to remove folder forcefully

# pwd: Present  working directory

# who am I: display the information of the current terminal  

# who : display all login user in the terminal.

# w : display logged users

# history: it shows all the command you have used.

History can store the last 1000 command which you have run. If you want to change

# vim /etc/profile


Save and exit

# history –c ( to clear all the previous command to reside in history)

# !! : repeat last command

# !r : the last command executed with ‘r’ character

# !20 : executed that no. of command

Moving And Renaming File And Directory

mv: move /rename files and directory

# mv [option] file destination

# mv old name new name

multiple files can be moved at a time if the destination is a directory

# mv [option] file1 file2 file3 destination

# mv [source add] [destination add]


The command that is used to get the help are discussed as:

# What is command: Display a short description of the command, it uses a database that is updated nightly. Often not available immediately after installation.

#  –help: Display usage summary and argument list

# man: for help

#info: for help

Both provide documentation for command. Almost every command has a “man” page. The collection of pages is called the Linux manual.

Viewing Text Page

#more [option] [filename]

#less [option] [filename]


# less abc.txt

scroll with arrows/PgUp /PgDown

we can also use “less” with pipe |

These are common commands of Linux to do practice of it after that we will continue to learn other Basic Linux commands in this linux tutorial like copy paste commands, process related command, networking related commands and many more.
