Problem

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.

Code

cnt=0
while read line && [ $cnt -le 10 ]; do
  let 'cnt = cnt + 1'
  if [ $cnt -eq 10 ]; then
    echo $line
    exit 0
  fi
done < file.txt
