New to Perl

[Soin, Harinder]

Hello All, 
I am new to perl and I am qucikly realizing that a solid understanding of
Regular Expressions is a necessacity. Can anyone point me a good source
where I can go from zero to 100 miles in a short period of time. Also, if
anyone can give me some info in the DBI module of perl, I will appreciate
it.
Thanks
Harry
