I was studying the command find, and I saw:

-cmin n
              File's status was last changed n minutes ago.
-ctime n
              File's status was last changed n*24 hours ago.

but when n is zero, comes the difference, is there a sound explanation for this behavior?

$ touch a 
$ find -name a -cmin 0
$ find -name a -cmin 1
./a
$ find -name a -ctime 0
./a
$ find -name a -ctime 1

  • Find results seems correct to me. – Alice Oualouest Jul 23 '20 at 06:22

  • The `-ctime` granularity is a whole day. So when you use `-ctime 0` it means any time from 0 days ago to 0.99999 days ago, and `-ctime 1` means from 1 day ago to 1.99999 days ago. – Barmar Jul 23 '20 at 06:27

    thank you for your guide, and i can understand the ctime , however similarly the cmin 0 shoud means 0 mins ago to 0.999 mins ago,but it doesn't – joker Jul 23 '20 at 06:33
