Thanks for the replies.
The problem is, these scripts are not under my control at all. I can only think from the point of view of the parent, I need to run these scripts, and they should never be allowed kill the parent. Is this possible do you think from the parents point of view?

VWRIGHT(1) General Commands Manual VWRIGHT(1)
NAME
vwright - normalize a RADIANCE view, shift it to the right
SYNOPSIS
vwright [ view options ] distance
vwright [ view options ] name
DESCRIPTION
In the first form, vwright shifts a RADIANCE view the specified distance to the right, putting out a complete set of view parameters in a
single line on the standard output. This utility is most often used to compute a right-eyed view from a left-eye view for stereo imaging.
If no options are specified on the command line, vwright reads a view from its standard input.
The distance given is in world coordinate units. A negative value indicates a shift to the left rather than the right.
The second form substitutes a name prefix in place of the shift distance, and produces constant assignments on the standard output suitable
for passing directly to rcalc(1). For a given prefix N, the constant names are as follows:
Nt: view type ('v'==1,'l'==2,'a'==3,'h'==4,'c'==5,'s'==6)
Npx: view point x value
Npy: view point y value
Npz: view point z value
Ndx: view direction x value (normalized)
Ndy: view direction y value (normalized)
Ndz: view direction z value (normalized)
Nd: view focal distance
Nux: view up vector x value (normalized)
Nuy: view up vector y value (normalized)
Nuz: view up vector z value (normalized)
Nh: view horizontal size
Nv: view vertical size
Ns: view shift
Nl: view lift
No: view fore clipping distance
Na: view aft clipping distance
Nhx: derived horizontal image vector x value (normalized)
Nhy: derived horizontal image vector y value (normalized)
Nhz: derived horizontal image vector z value (normalized)
Nhn: derived horizontal image vector multiplier
Nvx: derived vertical image vector x value (normalized)
Nvy: derived vertical image vector y value (normalized)
Nvz: derived vertical image vector z value (normalized)
Nvn: derived vertical image vector multiplier
EXAMPLES
To start rpict(1) on a view .06 meters left of the view in the file "right.vf":
rpict `vwright -.06 < right.vf` scene.oct > right.hdr &
To move the rad(1) view named "left" 2.5 inches to the right and render from there:
rad -v "right `rad -n -s -V -v left examp.rif | vwright 2.5`" examp.rif &
To pass a view to rcalc for conversion to some other view:
rcalc -n -e `vwright orig < orig.vf` -f viewmod.cal -o view.fmt > new.vf
