mount question

I am trying to troubleshoot an existing script and have
located the point of failure. Before I make any changes I
need to know what the bolded entry is doing/for:

mount /dev/dsk/$disk /mnt [b]2>/dev/null[/b]

I know that if I leave it off everything will work, but does
anyone have an idea what the bolded part is trying to do?

Thx!
DY

Yup, it tries to guide you to opsol-help (the forum/mailing
list)
where you can post as many help requests as you want.

Enough for constructive, helpful trolling.

Back to your question:
The 2 is the descriptor for the error output (stderr).
The > is redirecting all things to the following channel
or file.
The /dev/null is a device which is something like a black
hole in your unix system.

So, every error message is redirected into nothing.

Hi Doug.

It quiets error messages by routing stderr to the bit
bucket.

    Thanks,
