ref: nohup (GNU coreutils) 8.23
1] Wouldn't it be useful for nohup to indicate the PID of the process it
spawns?
1.1] What comes to mind would be to have nohup send the PID to
either STDOUT or STDERR, and also to send it as a first line to its
output file.
1.1.1] It would also be helpful for nohup to send to its output file
the text of the command line that it spawned.
1.2] This would be useful to help:
1.2.1] track the process
1.2.2] send it signals
1.2.3] identify what exactly this output file is recording
1.3] This behavior would be consistent with what bash does when ending
a comamnd with '&'; it indicates the PID and job number.
2.] Also, I would find it useful for nohup to have options to produce a
{quasi-,}unique output file:
2.1] nohup_${PID}.out
2.2] nohup_${PID}_${RANDOM}.out
For your consideration,
