Top Forums UNIX for Advanced & Expert Users Why is editing a file by renaming the new one safer? Post 303042599 by zxmaus on Wednesday 1st of January 2020 01:28:03 AM

I am largely with Neo - depending on what file you are modifying, you might not even need a backup copy at all. For example, I often create feeding files for loops - and afterwards modify them (add or remove things) - these are my very own files and I usually can recreate them very easily if I ever have to - so these I modify without any backups. System files however should always be modified after a copy - ideally a copy where ownership and permissions are the same as the original - so if anything ever goes wrong - all you have to do is rename the original file to something like .old and your copy to the original filename.
BTW - in 32 years, I have not lost a single file to a system crash.
