How to batch remove all lines after the nth line?

melanievt

I have a bunch of text files each having a different number of lines. I want to keep only the first 100 lines in each file. How can I do that?
Thanks in advance,
Mel

Find: \A(?-s)(?:^.*\R){100}\K(?s).*
Replace: nothing
Search mode: Regular expression

Suggest backing up all of your data before trying this.
