That doesn't quite match the OPs stated requirements in that it will preserve the entire 'line', (which could be the entire file if this was a binary file), containing the keyword rather than truncating immediately after the keyword.

Has the advantage that it does matter how big the file (assuming non-binary), or how far into the file the truncation point is.

Has the disadvantage that it will consume more disc space rather than reducing it--if that was the original intent.

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.
