What is Redirection Operator ?

Redirection Operator

Both the symbols > and >> are called redirection operators in Linux.

Redirection operator is used to save the output after running a command to a file.

Let us understand what these two operators are ?

1.  >  Operator


Whenever you run the command, then the output comes on the screen,  if you want to store the output on the screen in a file, then you can do it through this operator.

* This operator should be used only with commands that output to the screen. 

* It overwrites the output of the command inside the file.

*If the file does not already exist then it creates the file and then stores the output in this file.

Syntax :

$ (command ) > File_Name

Example:- 


Tittle : ls -l Command Output 

In above picture you can see the output of ls command, now we will store this output in a file. 


Tittle : uses of > operator 

Using this Redirection operator ( > ), we have directly stored the output in a file named "redirection.txt".


Tittle : redirection.txt

You can see in the above image that the output is saved inside the file.


Uses of  > Operator 

1. storing the output of a command inside a file.

2.  Creation of new file.

3. Copy the file using cat command '$ cat file1.txt  >  file2.txt'

2.  >> Operator 

It is also used to store the output of the command inside the file but instead of overwriting it, it appends the output inside the file.

* This operator should be used only with commands that output to the screen. 


* It appends the output of the command inside the file.


*If the file does not already exist then it creates the file and then stores the output in this file.


Syntax :

$ (command)  >> File_Name


It is also used like > operator but it appends instead of overwriting.
