jobs [ -dlprs ] [ job ... ]
jobs -Z string
       Lists information about each given job, or all jobs
       if  job is omitted.  The -l flag lists process IDs,
       and the -p flag lists process groups.   If  the  -r
       flag  is specified only running jobs will be listed
       and if the -s flag is given only stopped  jobs  are
       shown.  If the -d flag is given, the directory from
       which the job was started (which  may  not  be  the
       current directory of the job) will also be shown.

       The  -Z  option  replaces  the shell's argument and
       environment space with the given string,  truncated
       if necessary to fit.  This will normally be visible
       in ps (ps(1)) listings.  This feature is  typically
       used by daemons, to indicate their state.
