Greg,

Just curious -- in other regex implementations you have to "escape" the dot if you want it to match a literal period (dot) instead of any character. Does PCRE work the same way? I am always getting bit by this when I am trying to match IP addresses and domain names...

Ya you have to escape it if you wanna be sure it's a "DOT". You can try it with pcretest on your shell

[root at hera ~/netdisco]# pcretest PCRE version 4.5 01-December-2003

re> /\d\.\d.\d/ data> 1.234
0: 1.234 data> 123.4 No match data> 1.2.3 0: 1.2.3 data> 12345 No match

So you can see that "\." will match exactly a DOT not any other

character as "." will do.
