I am confused about your intent for redirection of stdout to tempfile:

perl-script doesn't get any input data.

Are your intermediate files large enough so that writing them to disk 
and reading back is an issue? If you just want to streamline the process 
so that you don't have to go to shell and back to octave and back to 
shell again, you can call your programs from octave using the system() 
function. You can even capture the stdout of the program :

[status,output]=system('mycommand')
