jobs produces a list of the processes in the current session. Each such process is numbered for easy identification by kill and is described by a line of information:
[job-identifier] default state shell_command
is a decimal number which identifies the process. When you use the job-identifier as an argument to the commands or to jobs, preface the number with %.
identifies the default process (that is, the most recently suspended process). If default is a +, this process is the default job. If default is a -, this job becomes the default when the current default job exits. There is at most one + job and one - job.
shows a job as:
is the associated shell command which created the process.
also displays the process group ID of a job (before state).
displays jobs that have changed states and free dead jobs.
displays only the process IDs of all processes.
Possible exit status values are:
POSIX.2. x/OPEN Portability Guide 4.0. Windows 7. Windows Server 2008 R2. Windows 8. Windows Server 2012. Windows 10. Windows Server 2016.
jobs is provided as a MKS KornShell built-in only.
You cannot use | to pipe output from jobs to another command and get useful results. The jobs reports the status of background jobs in the current shell; however, when you use the pipe operator, jobs is actually run in a new shell, which does not have background jobs, so it cannot report on any. You can, however, use > to redirect jobs output to a file which can then be used as an input file by another command.
