Re: How do I delete from a delimiter to the end of a file?

I actually like ikegami's solution better, but this is what I thought of first:

perl -pi -e 'BEGIN{$/="\cB"} s{-{6}\sYahoo.*\z}{$/}ms' list of files

I suspect yours will work better than ikegami's in a large number of situations. Reading 20k messages one-at-a-time is likely a better idea than requiring the entire archive of 20k messages to be read into memory at once. Yours is even a complete example, not just a single regex that leaves the process of replacing files and slurping as an exercise. - tye	[reply]
