Apa arti angka-angka di kolom status daftar launchctl?

launchctl memiliki kolom "Status" di output daftar launchctl. Halaman manual atau salah satu halaman peluncuran launchd terkait tidak menyebutkan kolom ini atau apa artinya.

Ini adalah kode keluar terakhir dari layanan itu.

The launchctlhalaman manual menggambarkannya.

 list [-x] [label]
          With no arguments, list all of the jobs loaded into launchd in
          three columns. The first column displays the PID of the job if
          it is running.  The second column displays the last exit status
          of the job. If the number in this column is negative, it repre-
          sents the negative of the signal which killed the job.  Thus,
          "-15" would indicate that the job was terminated with SIGTERM.
          The third column is the job's label.
