Find Files Modified After Specific Time

If you have GNU find, then there are a legion of relevant options. The only snag is that the interface to them is less than stellar:

-mmin n (modification time in minutes)
-mtime n (modification time in days)
-newer file (modification time newer than modification time of file)
-daystart (adjust start time from current time to start of day)
Plus alternatives for access time and 'change' or 'create' time.
The hard part is determining the number of minutes since a time.

One option worth considering: use touch to create a file with the required modification time stamp; then use find with -newer.

touch -t 200901031231.43 /tmp/wotsit
find . -newer /tmp/wotsit -print
rm -f /tmp/wotsit

This looks for files newer than 2009-01-03T12:31:43. Clearly, in a script, /tmp/wotsit would be a name with the PID or other value to make it unique; and there'd be a trap to ensure it gets removed even if the user interrupts, and so on and so forth.

Below is an example of how to move files that are older than 30 days :

find /storage/current/dbdumps/ -type f -mtime +30 -print | xargs -I {} mv {} /storage/archive/dbdumps
