Same as rm -rf / eh?
There is also the issue/argument to use xargs instead of exec, speed... exec
spawns a process for each iteration I believe. There has been discussions on
this forum, so probably could google archives if interested. (I am using exec
in a lot of circumstances, but I forgot why).

You are aware, as I was not, that "-mtime+1" means "one day ago, from the
moment I typed this command"?
The above command, if executed at 07:30:34 on 22 August 2011, will keep all
files dated 07:30:34 from 21 August 2011 and later? One day ago is taken
literally in this case.
Have you checked to be sure that the files remaining after the command has
executed do actually meet the criteria of being older than 24 hours? One other
thing, I'd be loath to run that command myself (experience!) as in the unlikely
event of £EXPORT_DIR not having a value, and you being in / as root, bad things
will happen! How do I know? :-(
Cheers,
Norm.
