### 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
```console
$ ./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`.
