Subject: Regular Expressions

Hello! I'm trying this problem that says I must match versions in a CSV
file,

could be anything like:

v.6.0.3-3
aajd4-43_3
ABCD 5.0
ABCDv.5.0
A 3.40
...

With the other fields in mind, I thought "heck, looks like versions are
the only ones that contain a series of letters, digits, periods,
underscores and dashes..."

I'm pretty new to Ruby so I don't have very much experience with regular
expressions. Is it possible to make just one regular expression to
fulfill my problem? I need a regular expression that will return:

v.6.0.3-3: true because there's a v followed by a series of '.' and
digits
aajd4-43_3: true because there's a series of digits, '-', and '_'
ABCD 5.0: true because there's a series of digits and '.'
ABCDv.5.0: true...
A 3.40: true...

Thanks for the help!
