Re^2: Searching and Replacing file content within directory

Your guess is correct - setting $^I to an empty string overwrites the original file, no backups.

Thanks for confirming that. Just one correction: there's never any "overwriting" of the original file--a new file is always created. It's just that when you assign a blank string to $^I, perl doesn't save a copy of the original file before renaming the new file to the original file name.	[reply]
