This is a question about VI Editor.
So when you want to replace single character with multiple character at that time we use 's'.
So when you want to replace single line with another line at that time we use 'S'

sed -i 's/ugly/beautiful/g' text.txt

text.txt is the input file.

Here s is used to replace the characters.

It is referring inline command (i.e start with esc and colon).

Ex1: s/+/ /g.

This command replace all plus (+) sign present in the file with space.

Ex2: s/I/You/g.

This command replace all "I" present in the file with "You".

It should be 'r'. After replacing with single character vi returns to command mode, so 'r' is more accurate than s.
