Impossible. exec only accepts a single command.

If you believe that I am mistaken, refer yourself to the documentation of the exec system call interface which is wrapped by the exec shell builtin.

If you aren't sure about your script, post it. Vague concerns about instances of ksh in the process list is not a good reason to overcomplicate an implementation.

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.
