Chapter 17 Finding Files with find |
|
The times that go with the find operators -mtime , -atime , and -ctime ( 17.4 ) aren't documented very well. The times are in days:
A number with no sign, for example,
3
(as in
-mtime 3
or
-atime 3
), means the 24-hour period that
ended
exactly three days ago (in other words, between 96 and 72 hours ago).
A number with a minus sign (
-
) refers to the period
since
that time. For example,
-3
(as in
-mtime -3
) is any time between now and three days ago (in other words, between 0 and 72 hours ago).
Naturally, a number with a plus sign (
+
) refers to the 24-hour period
before
that time. For example,
+3
(as in
-mtime +3
) is any time more than three days ago (in other words, more than 96 hours ago).
Got that? Then you should see that -atime -2 and -atime 1 are both true on files that have been accessed between 48 and 24 hours ago. ( -atime -2 is also true on files accessed 24 hours or less ago.)
For more exact comparisons, use find -newer with touch ( 17.8 ) .
