I'm almost embarassed to ask... But is there a place where one can read about the symbols: ~ ^ \ $ ? + and what they do/mean?
For example, consider this following line:
if (!(uri =~ "^sip:.+@(255.255.255.255|(sip.|sip5.)?mydomain.com):5080$"))
It looks like, to me, that it's checking to make sure that uri is NOT equal to any of combination of the data following the @ - but I'm not so sure exactly what I'm reading. ie: the ~ after the =, the ^ in front of sip, the .+ in front of @, the ? before mydomain and the trailing $.... And why the period has the \ in front of them all...?
Yes, I'm totally green at this stuff. :( Thanks in advance for your help...
