Homework & Coursework Questions

That's your login shell, not what you're using in your shell script.

I see #!/bin/sh at the top of your script. sh might be bash on your system -- or it might not. It might even be dash on some systems, which has almost no features... Try #!/bin/bash

Yea I can do redirection doing simple things like that. but yea it's from 2000 I think.

Okay, you're on Solaris. That means #!/bin/sh isn't bash. It's not even proper POSIX. You're getting Sun's weird old "backwards compatible" shell, barely younger than Disco. If you're allowed to use BASH, even the ancient version they have(you're using 2.0, we now have 4.0) is about 20 years newer.

The read + temporary file trick should work in either shell I think, but "<<<" definitely won't.

You should ask your prof which shell you're supposed to be using, since solaris #!/bin/sh is especially painful.

You should also be very grateful that you have GNU date.

Yes it really is. I run Ubuntu and have the stuff I do I have to rewrite to wok on the Solaris shell to work.

If I had to guess, I'd think that maybe expr is throwing up on the leading 0 in hour, but I have no way to test that, I don't have access to a solaris system anymore.

I got it. It was pretty easy once I took a minuet to look over the code but now I'm trying to at a argument and assign it to a perimeter where it has to be a number. like 1-24 but i get errors.

Please show the current version of your script and the exact error message which you received.


Slightly off-topic. On this vintage of Solaris surely Korn Shell would be more reliable ... and easier for others to present code which will run.

Code:

#!/usr/bin/ksh
