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...
