This will normally be visible in tt(ps) (manref(ps)(1)) listings. This feature is typically used by daemons, to indicate their state. + +Full job control is only available in the top-level interactive shell, +not in commands run in the left hand side of pipelines or within +the tt(LPAR())var(...)tt(RPAR()) construct. However, a snapshot +of the job state at that point is taken, so it is still possible +to use the tt(jobs) builtin, or any parameter providing job information. +This gives information about the state of jobs at the point the subshell +was created. If background processes are created within the subshell, +then instead information about those processes is provided. + +For example, + +example(sleep 10 & # Job in background +LPAR() # Shell forks +jobs # Shows information about "sleep 10 &" +sleep 5 & # Process in background (no job control) +jobs # Shows information about "sleep 5 &" +RPAR()) ) findex(kill) cindex(killing jobs) |
