Split, edit then unite large text files

I have a need to text search and replace a very large text SQL file. The editing is pretty simple. For example, replacing “site1.com” to “site2.net”.

I did that with by lines splitting, editting them with an editor and uniting them. I got a checksum error. Of course there must be checksum error because pieces have been edited. That part I understand but my question is the result file of the uniting can be used, same as if I have an editor that can handle huge files?


You are right, the checksum error is due to editing. However, GSplit does not cancel the uniting process anyway (unless you accept to abort it) so you can reuse the result file. Of course, the result file is the one with the changes you made.
