How to grep hyphen ('-') in a string?

[William Tang]

I have a string such as:
XYZ-ABC.xml NEW 1.0 myfolder/mylocation wtang.001

I use the following grep function try to grep it:
grep(/^\s*\w+\.\w+\s+([0-9\.]+|New)\s+[0-9\.]+\s+[\w\\\/\.]+\s+\S+\s*$/,
<SCRFILE> );

where <SCRFILE> is the filename that store this string.

It seems that it can't read this '-'. If I change it into '_', it
works fine.

Did I missing something?

Thanks,
William

Yes. You missed the fact that \w does not match a hyphen. \w matches
letters, numbers, and the underscore.
