Running Jobs in the Background with bg


Running Jobs in the Background with bg

If you're running a job that doesn't require input from you, consider running it in the background using bg (Code Listing 9.7). In doing so, you can keep the program running while working on other Unix activities at the same time.

Code Listing 9.7. Restarting suspended jobs in the background lets you do two thingsor moreat once. To move a job to the background, just type bg followed by % and the job number.

[ejr@hobbes ejr]$ jobs [3]- lynx http://www.raycomm.com/ &   calvin.raycomm.com [2] Stopped (tty input) telnet [3] Stopped (signal)    lynx   http://www.raycomm.com/ [4]+ Stopped  man  telnet [ejr@hobbes ejr]$ bg %3 [3]- lynx http://www.raycomm.com/ & [ejr@hobbes ejr]$ 

To run jobs in the background with bg:

1.

jobs

At the shell prompt, type jobs to see the list of all jobs, running or stopped. Note the job numbers on the left.

2.

bg %3

Type bg followed by % and the number of the job you want to run in the background Code Listing 9.7.

Tips

  • If you want to put the most recently suspended job into the background, just type bg (without the number) at the prompt.

  • You can also put jobs directly into the background without first suspending them. Just type the name of the job to run, a space, and & (as in bigdog &). The & moves the job directly into the background.
