The ABC's of grep - N

N

We have arrived to a flag that I pretty much use all the time. The -n shows you the line number​ of the found search pattern.

Ok, back to our test.txt file with the following content:

sad
happy
awake
coffee
work
school

Using the -n flag we can find exactly which line “coffee” is on:

$ grep -n "coffee" test.txt
4:coffee
