Yup, but you should already know that it is. But of course the command alone isn't enough.
Variable not Defined wrote:So, I'm a little comfused. I run linux as my main OS so I know most of the commands. Did a little research and learned the commands for perl. Not one combintation, I tried ~20 different ways, with not one doing what it's supposed to. I still get a white screen with reference to cal.pl instead of... you get the point I hope. Don't want to test the boundries with what I put here.
Reread the thread, there should be enough hints already and check your spelling if English is your first language (if not, don't worry about it). As you run Linux, run the cal command and see what happens, then run another command. Try to do this as efficient as possible. You might even want to recreate the perl script to test it, though it isn't necessary. Think how the input gets used for the output.
