 From the help file for system():

      If ‘intern = FALSE’, the return value is an error code (‘0’ for
      success), given the invisible attribute (so needs to be printed
      explicitly).  If the command could not be run for any reason, the
      value is ‘127’.

so not having the command in your path does not give status 1 ....

This is off-topic here: you need to consult the documentation of the 
command you run to see its error codes.  (On Linux 'man octave' does not 
say, although it would be expected to.)
