Tenth Line

Tenth Line

Given a text file file.txt, print just the 10th line of the file.

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

Note: 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.

Solutions

💲 Bash

# Read from the file file.txt and output the tenth line to stdout.
if [ $(wc -l file.txt | cut -f1 -d' ') -gt 9 ]
then
    cat file.txt | head -n 10 | tail -n 1
