-mtime n: n is a number, meaning a file that has been modified (modification) within one day before n days.

-newer file: file is an existing file, meaning that as long as the file is newer than file, it will be listed.

-name filename: search for a file named filename

-size [+ -] SIZE: search for files larger (+) or smaller (-) than SIZE. The specifications of this SIZE are: C: for byte,k: for 1024bytes, so to find a file larger than 50KB, it is "- size + 50K"
