Subject: Regex: What does the ^ do?  What is it called?

Hello,

Im trying to understand what the ^ and $ characters do when used in
regular expressions.

For example:

/^abc/ =~ "!abc"
returns nil
"You can use an anchor to match the beginning of a string"


/abc$/ =~ "abc!"
returns nil
"You can use an anchor to match the end of a string"


Why do these two statements return nil and how does the "anchor" work
exactly?

Can someone please clarify?


Does this mean that the regex is checking before the C\d+ ?
if @refdes[0] =~ /^C\d+/
      return "Capacitor"

Thanks in advance.
