To find all files modified within the last 5 days, use the following:

find / -mtime -5 -print

The – in front of the 5 modifies the meaning of the time as “less than five days.” The following command displays files modified more than five days ago:

find / -mtime +5 -print

Without the + or -, the command would find files with a modification time of five days ago, not less or more.
