[Techtalk] Bash builtin "read" isn't working like I expect

In RegularExpression syntax the dot . means "any character",
so it would match a "." character, too. So, no major problem here.

Okay, maybe...
If $LINE contained a \n at the end, then the grep expression would, too.
You'd then have to strip away the \n.
I checked that and it doesn't seem to be the case. But maybe you have
another bash version, which does act like this.

What is printed if you run a grep like this?
   grep "bank.com" master.csv

I'm sorry, I have to leave and won't be back before midnight (CET, that is
:-)...
I hope you find the solution!
