How do you find the timestamp of a file in Unix?
The command is called stat . If you want to adjust the format, refer to the man pages, since the output is OS-specific and varies under Linux/Unix. Generally, you can get the times through a normal directory listing as well: ls -l outputs last time the file content was modified, the mtime.
How do I find files older than a certain date in Unix?
this find command will find files modified within the last 20 days.
