A start would be with the find command. To find all files in your home
directory modified within the last 10 days and do an "ls -l" on them:
find ~ -mtime +10 -exec ls -l {} \;
The "+10" is for more than 10 days ("-10" would be for less than 10
days), the {} will be replaced by each file found. The escaped ";"
ends the parameter list to find.
Change the "ls -l" to whatever command you like. However, moving files
in subdirectories to corresponding target subdirectories will take a
bit of finesse. You may want to use a function that parses the file
name and makes non-existant subdirs before doing the move.
I bet someone here has a really clever way of doing that. ;)
