Re: [Help-bash] BASH quotation question...

[Roman Rakus]

You can follow my golden rule: double-quote every (not only) variable 
expansion.
It means, whenever you have dollar sign in your script encapsulate it to 
double quotes.
example:
var=foo
echo "$var"

It will be doing what you want in 99% of situations.
