... having tested this myself it is not what I see for foo. I see that foo.bak has the inode of the old foo. Are you sure of your result?

Well, maybe I was so tired that I didn't notice it was actually different. Here's what I got:

[j41r@work perl]$ rm alpha/foo.bak
[j41r@work perl]$ stat -c%n:$'\t'%i alpha/foo*
alpha/foo:      9353128
[j41r@work perl]$ perl -i.bak -pe 1 alpha/foo
[j41r@work perl]$ stat -c%n:$'\t'%i alpha/foo*
alpha/foo:      9353126
alpha/foo.bak:  9353128
[j41r@work perl]$ rm alpha/foo.bak
[j41r@work perl]$ stat -c%n:$'\t'%i alpha/foo*
alpha/foo:      9353126

Why did we get a different result than the one in file-dir-perms?
