How to display/print nth line in Linux Command Line [Quick Tip]

Problem:

Imagine a scenario where you need to print or display only the nth line of the file. For e.g, suppose you have a file with 50000 line and you want to print just the 100th line.

Solution.

My favorite way to do so is by using a combination of tail and head command. Here is the commands that can be used for the mentioned purpose:

tail -n +100 filename | head -n1

Tail -n +100 gives all the lines starting from 100th line. Then we use head -n1 which gives the first line. A combination of bot gives the 100th line.

The example can be made generic by replacing 100 by your desired value.
