1. Load the smaller (to-be-removed) list into a hash, having stripped any extraneous bits (eg. say $line =~ s[</+$][];) and having lc'd them.
  2. Read the bigger file line by line; strip any extraneous bits & lc them; if email read exists in the toBeRemoved hash, don't print it; otherwise do.
  3. Redirect the output to a temp file. Delete the original master file; rename the temp file to the master.
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

RIP Neil Armstrong
