How would I do regex matching in Erlang?
All I know is this: f("AAPL" ++ Inputstring) -> true.
The lines that I need to match "AAPL,07-May-2010 15:58,21.34,21.36,21.34,21.35,525064\n"
In Perl regex: ^AAPL,* (or something similar)
In Erlang?

A:
Use the re module, e.g.:
...
String = "AAPL,07-May-2010 15:58,21.34,21.36,21.34,21.35,525064\n",
RegExp = "^AAPL,*",
Options = [],
case re:run(String, RegExp, Options) of
match -> ... ;
nomatch -> ...
end,
...

Equivalent to `re:run(String, RegExp)`

How is this different to running => regexp:first_match(Line, "^AAPL,*" ) ?

Well, it may not be different, but according to the regexp module documentation 'it has been obsoleted by the re module and will be removed in a future release'. So, you should definitely prefer the re module.
