bash isn't Perl

Can you find my mistake?

#!/bin/bash
today = $(date +%Y-%m-%d)
echo $today

It took me a few minutes to realize what I had done.

s/\s*=\s*//;

I still get caught by that in ksh. My other favorite shell mistake:

$var="value"

Oops, make that:

s/\s*=\s*/=/;

And the title was supposed to be bash => perl, but it may as well be the above. I should take more time to review my posts before I post :-)

Yep. I often find myself adding whitespace where it doesn't belong. I should be able to spot these mistakes immediately after this many times. :)
