  • A log file with one line per background process is nice, as you can grep or count the tightly structured records.
  • But file per process in the background in a dedicated directory is the most popular.
  • I often set processes like these in a tree of pipes, using both | and <() and occasionally >() to tie all the processes together. This ensures no latency to speak of and no polling. When the process ends, it closes stdout and that releases the reading process.

Hi DGPickett,

I often set processes like these in a tree of pipes, using both | and <() and occasionally >() to tie all the processes together. This ensures no latency to speak of and no polling. When the process ends, it closes stdout and that releases the reading process.


Can you please provide a example of the 3rd point you referred if possible.

Thanks,
Regards,
karthikram
