My implementation of the Unix utility head, that prints the contents of a file.

Support for:

• standard input to print
• n arguments to display an limited number of lines
• c arguments to display an limited number of bytes
• multiple files to print

Print the standard input:

cargo r --release

Print the multiple files:

cargo r --release -- text.txt text2.text

Print the N first lines of a file:

cargo r --release -- text.txt -n <N>

Print the N first bytes of a file:

cargo r --release -- text.txt -c <N>
