[plug] Re: perl program to strip blank lines from a file

[J Michael Gilks]

Sorry, should take more care.
That one will of course only find a blank line with one space, as you pointed

To find a blank line with zero or more white spaces the pattern is
/^\s*$/
The asterisk is zero repititions, the plus sign is one or more repititions.

Love
Mike.
