The command head can be used to print the first few lines of a file.
The default use of head with print the first 10 lines of the file, but a flag
can be used to print more or fewer lines.
$ head -n 25 fake_data_file.txt
Use of -n 25 will print the first 25 lines, as opposed to the original 10.
Otherwise, default use would be:
$ head fake_data_file.txt
