##################################################################################

#

# 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.

##################################################################################

#!/bin/sh

# Read from the file file.txt and output the tenth line to stdout.

# Solution One

awk 'NR==10{print $0}' file.txt

# Solution Two

sed -n '10p' file.txt
