@Corona688, According to my script i have to redirect the various output to different files, so i have given the logfiles name explicitly. I will consider to use $$ PID in my logfiles.
When multiple files are involved I often do /tmp/$$-loggerdata, /tmp/$$-output2, and so forth. Don't forget to delete them when no longer needed or you'll have a mess.

This would be far better than just making exclusion, you'll be improving the usability of your program and removing a lot of potholes.

pfsinhdrgen(1)						      General Commands Manual						    pfsinhdrgen(1)

NAME

       pfsinhdrgen - Create a pfs stream with different exposures defined by hdrgen script.

SYNOPSIS

       pfsinhdrgen <sample.hdrgen>

DESCRIPTION

       This  program  reads  files  defined  in  given	hdrgen script and outputs them in a PFS stream. Each frame has a tag BV with corresponding
       brightness value (APEX standard). Larger BV corresponds to less exposure (darker image), necessary to capture a bright scene.

       The generated PFS stream is to be used with photo-metric calibration software and with generators of HDR images.

       HDRGEN script file is a plain text file in  which  each	line  contains:  <path_to_an_image>  <inverse_of_exposure_time_in_seconds>  <aper-
       ture_size> <iso_speed> 0

       In  most  cases	it  is	convenient to use the jpeg2hdrgen program to create such a file automatically. In case it could not parse the exif
       information from jpeg files, it is necessary to create this file by hand. Below are the sample contents of such file:

       <--- cut here: sample.hdrgen /var/tmp/images/img08.jpg 4 2.8 100 0 /var/tmp/images/img09.jpg 58.8235 2.8  100  0  /var/tmp/images/img10.jpg
       76.9231 2.8 100 0 /var/tmp/images/img11.jpg 322.581 2.8 100 0 /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen

EXAMPLES

       pfsinhdrgen sample.hdrgen | pfsview

	      View exposures defined in sample.hdrgen script.
