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.
