Only hardlinks, which are rare for scripts in my experience, and not symbolic links.
I have used the same overwrite-by-rename technique in very long-running embedded processes because renaming a file is atomic on common local Linux filesystems.
- fl0wenol 7y agoIn vim, it depends on the value of backupcopy. If set to "auto" (a default-default on linux, but maybe not for a specific distribution's default vimrc), the behavior is to check to see if the number of hardlinks to a file is greater than one, and then write the modified version in place, otherwise use the write and rename strategy.
