Write a Perl script that prints the contents of a file, prefixing each line with a line number. The script should accept exactly one argument representing the name of the file.

The script should be able to handle the following error conditions:

o Incorrect number of arguments

o The specified argument is not a file.

You cannot use the UNIX cat command in this assignment. You must use Perl to read the file and count the lines.

You cannot use the UNIX nl command in this assignment.

The printf function in Perl is useful for formatting numbers.

The script file name must be: linenum.pl

The script must be located in $HOME/itec400/homework

Make sure the permissions on the your itec400 directory are 705

Make sure the permissions on your script are 705
