The Times that find Finds

                                                  The Times that find Finds

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.)
