Instructions

Create a file left.sh that will pass the content of a file facts to a command that will return the number of lines in that file.

Usage

$ ./left.sh
21

Hints

To pass the content of a file to a command in a shell, you can use the < operator followed by the name of the file. For example, to pass the content of a file named input.txt to the cat command, you can use the following command:

cat < input.txt

The wc command is a utility in Unix-like operating systems that is used to count the number of lines, words, and bytes in a file or group of files. The -l option tells wc to only print the line count for each file.

For example, if you have a file called file.txt and you want to count the number of lines in the file, you can use the following command:

wc -l file.txt

This will print the line count for file.txt.
