linux - Find and replace text in a file between range of lines using sed

Question

I have a big text file (URL.txt) and I wish to perform the following using a single sed command:

1. Find and replace text 'google' with 'facebook' between line numbers 19 and 33.

2. Display the output on the terminal without altering the original file.

Answer 1

You can use sed addresses:

sed '19,33s/google/facebook/g' file

This will run the substitution on lines between and including 19 and 33.

The form of a sed command is as follows:

[address[,address]]function[arguments]

Where 19,33 is the addreses,
substitute is function
and global is the argument
