  • First thought: Why in the world is this a perl script?
  • Second thought: don't use ls -h: some files might have a suffix of M; some G (etc). No good.
  • Third thought: Why are you doing this? Whatever the reason, I think there has got to be a better way. You do not need to be searching your WHOLE filesystem every minute (I'm assuming that's what you're doing based on your find options). With the limited info you've given, I think you would be much better off installing inotify-tools (available in every major distro) and watching only the directories that things are being created in.

aa-exec

AA-EXEC(8)							     AppArmor								AA-EXEC(8)

NAME

       aa-exec - confine a program with the specified AppArmor profile

SYNOPSIS

       aa-exec [options] [--] [<command> ...]

DESCRIPTION

       aa-exec is used to launch a program confined by the specified profile and or namespace.	If both a profile and namespace are specified
       command will be confined by profile in the new policy namespace.  If only a namespace is specified, the profile name of the current
       confinement will be used.  If neither a profile or namespace is specified command will be run using standard profile attachment (ie. as if
       run without the aa-exec command).

       If the arguments are to be pasted to the <command> being invoked by aa-exec then -- should be used to separate aa-exec arguments from the
       command.
	 aa-exec -p profile1 -- ls -l

OPTIONS aa-exec accepts the following arguments:
       -p PROFILE, --profile=PROFILE
	   confine <command> with PROFILE. If the PROFILE is not specified use the current profile name (likely unconfined).

       -n NAMESPACE, --namespace=NAMESPACE
	   use profiles in NAMESPACE.  This will result in confinement transitioning to using the new profile namespace.

       -f FILE, --file=FILE
	   a file or directory containing profiles to load before confining the program.

       -i, --immediate
	   transition to PROFILE before doing executing <command>.  This subjects the running of <command> to the exec transition rules of the
	   current profile.

       -v, --verbose
	   show commands being performed

       -d, --debug
	   show commands and error codes

       --  Signal the end of options and disables further option processing. Any arguments after the -- are treated as arguments of the command.
	   This is useful when passing arguments to the <command> being invoked by aa-exec.
