Top Forums UNIX for Advanced & Expert Users Why is editing a file by renaming the new one safer? Post 303042579 by MadeInGermany on Monday 30th of December 2019 11:04:48 AM

They mean: copying a file, especially a big file, is done in steps. If there is a power loss in between, the status of the file is unknown: can be empty or partially copied.
In contrast, renaming/moving a file is "atomic": after a power loss it's either 100% the new file or 100% the old file.

But with a copy speed of >100 Mbyte per second and "journaling" it is a bit paranoid to assume a power loss within these microseconds, IMHO.
So that's why I prefer to keep the inode intact (including attributes and link count), and simply assume that power will last for the next microseconds.
