... 2 April 1999 . The Nobeyama Radioheliograph data show that in the microwave range, besides large-scale trans-equatorial chains (see, e.g., the May 11-15, 1993 and November 1-4, 1993 events), there are also many examples displaying large and strongly evolving "longitudinal" or "internal" chains connecting remote active regions inside an active zone in one (northern or southern) hemisphere (the August 20-September 3, 1998 event). ...

. To display the state of any background jobs that you are currently running use the job command. For example: jobs [1] + Running xterm -g 90x55 [2] - Running xterm -g 90x55 . This displays the job number, its state and the command associated with this job. To display the process number use the -l option. For example: jobs -l [1] + 3584 Running xterm -g 90x55 [2] - 3587 Running xterm -g 90x55 .
