Tenth Line - Leetcode Solution

Problem Statement:

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

Example:

Suppose 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
Line 11

The output should be:

Line 10

Solution:

This problem can be solved using the head and tail commands in Linux.

The head command displays the first 10 lines of a file, while the tail command displays the last 10 lines of a file. We can use the tail command to display the last line of the first 10 lines of the file.

The command to solve this problem is:

tail -n +10 file.txt | head -n 1

Explanation:

• The tail -n +10 file.txt command displays all the lines in file.txt starting from the 10th line.
• The | character is used to pipe the output of the previous command to the next command.
• The head -n 1 command displays only the first line of the output from the previous command, which is the 10th line of the file.

Note: This solution assumes that the file has at least 10 lines. If the file has less than 10 lines, the command will not produce any output.
