Find all the files and directories in the demo directory that are newer than s1. Send the output of the command to /var/tmp/t1 (don't send it to the demo directory). The names of the files should appear as full names. For example, the file "s5" would appear as "/home/demo/s5". The "/home/demo", if it appears in the output, should not have a trailing "/". The secret to avoiding the trailing slash is to use "/home/demo" not "/home/demo/" in the find command.
