How to use vim command

VIM: Search and replace syntaxThe syntax is as follows:

:s/Search/Replace/CommandFlag
:s/Search-Word/Replace-Word/g
:%s/Search-Word/Replace-Word/g
:%s/Search-Word/Replace-Word/gc

Example:

To find each occurrence of ‘eth0’ in the current line only, and replace it with ‘br0’, enter (first press Esc key and type):
:s/eth0/br0/g

To find and replace all occurrences of ‘eth1’ with ‘br1’, enter:
:%s/eth1/br1/g

To find and replace all occurrences of ‘eth1’ with ‘br1’, but ask for confirmation first, enter:
:%s/eth1/br1/gc


To find and replace all occurrences of case insensitive ‘eth1’ with ‘br1’, enter:
:%s/eth1/br1/gi

The above example will find eth1, ETH1, eTh1, ETh1 and so on and replace with br1. To find and replace all occurrences of ‘eth1’ with ‘br1’ for lines from 3 to 7, enter:
:3,7s/eth1/br1/g
