Option: -daystart
Measure times from the beginning of today rather than from 24 hours ago.
So, to list the regular files in your home directory that were modified yesterday, do
find ~/ -daystart -type f -mtime 1
The ‘-daystart’ option is unlike most other options in that it has an effect
on the way that other tests are performed.
The affected tests are ‘-amin’, ‘-cmin’, ‘-mmin’, ‘-atime’, ‘-ctime’ and ‘-mtime’.
The ‘-daystart’ option only affects the behaviour of any tests which
appear after it on the command line.
