output of jobs command

jhwilliams · 06-23-2007, 12:17 AM

Code:

[root@sage gz_files]# jobs
[1]   Running                 tar -czf mp3.tar.gz ../Media/MP3/ &
[2]-  Running                 tar -czf pictures.tar.gz ../Media/Pictures &
[3]+  Running                 tar -czf audio.tar.gz ../Media/Audio/ &

what are the plus and minus signs for?

man jobs doesn't hurt

Quote:

The character '+' identifies the job that would be used as default for the fg or bg utilities; this job can also be specified using the job_id %+ or "%%" . The character '-' identifies the job that would become the default if the current default job were to exit; this job can also be specified using the job_id %-.

my man pages had jobs under bash bulletins ... didn't seem to have any info on the +/-. Probably should have looked for a different manual version online before coming here... Thanks for the answer though!

Yup ... a bash built-in.

Of course RedHat may have fubared the man-pages for bash ...
