Shell Programming and Scripting

Im trying to diff two files. The first one I will be given. The second one I must find based on previous version created.

For instance here are the files

file_1 - created 3/22/08
file_2 - created 3/23/08
file_3 - created 3/24/08
file_4 - created 3/25/08

then I put in this code
" find . -name 'file_*' -mtime -1 -print > most_recent_file "
this finds any file in the previous directory that contains file_* from 1 day ago and prints it to most_recent_file

now my question is, is there a way I can diff this file with the previous version file_3

Code:

ls -1tr file_* | tail -1

will give you the latest file. save that result to a variable, then you can start using diff.
