If the files aren't huge, or the word appears fairly early (a few hundred MB) in the file, then you can do this with a "one-liner" (wrapped for viewing; adjust quoting to your OS needs): 

perl -e"BEGIN{$/=qq[the word or phrase]}" 
-ne"$n=tell ARGV; close ARGV; truncate $ARGV, $n" path\to\the\file

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
