TenthLine.sh

#!/usr/bin/env bash

#How would you print just the 10th line of a file?
#
#For example, assume that file.txt has the following content:
#
#Line 1
#Line 2
#Line 3
#Line 4
#Line 5
#Line 6
#Line 7
#Line 8
#Line 9
#Line 10
#Your script should output the tenth line, which is:
#Line 10
#[show hint]
#
#Hint:
#1. If the file contains less than 10 lines, what should you output?
#2. There's at least three different solutions. Try to explore all possibilities.

awk 'NR == 10' file.txt
