<DIV><FONT face=Arial size=2> I'm almost embarassed to
ask... But is there a place where one can read about the symbols:
~ ^ \ $ ? + and what they
do/mean?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> For example, consider this
following line:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> if (!(uri =~
"^sip:.+@(255\.255\.255\.255|(sip\.|sip5\.)?mydomain\.com):5080$"))</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> 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...?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Yes, I'm totally green at this
stuff. :( Thanks in advance for your help...</FONT></DIV>
