Writing to files – the w command

The sed command for writing is w. Using this command, we can write lines from one file to another file.

Here is an example:

    $ cat new.txt 
  

The output is as follows:

    new is a empty file
    
    $ sed -n '/Chicken/w new.txt' shopping.txt
    $ cat new.txt 
    Chicken    3    5    15
  

After the w command, we specify the file to which we will perform the write operation. In this example, the line containing the Chicken pattern is written to the new.txt file.
