As already stated, this is a perfect task for
cron and
find if they are available on your system.
The appropriate (but untested) find command will probably be:
find /path/to/dir -type f -atime +10 -exec rm {} \;
If you don't have
find available, you could accomplish the same thing with the
find2perl and
File::Find (as mentioned above). There are a couple other modules that have nicer (in my opinion) interfaces to File::Find:
File::Finder or
File::Find::Rule). For instance, (using
File::Find::Rule):
use File::Find::Rule;
File::Find::Rule->file() # only files
->atime("+10") # that haven't been accessed in 10 days
->exec( sub { unlink( $_[2] ) } ) # delete them
->in('/path/to/dir'); # starting in this path
Regardless of how you implement the
find functionality, you'll need some other scheduling utility (like
cron) to handle the "perpetual" part of your question.
