Shell Programming and Scripting: Resuming Stopped Unix Jobs
To resume a stopped Unix job, follow these steps:
1. Use the jobs -p command to list all stopped jobs and their process IDs.
2. Identify the job number of the desired job from the list.
3. Bring the job to the foreground using the fg %job_number command. This will make it active in the current shell session.
4. Alternatively, you can run the job in the background by using the bg %job_number command.
5. If you want to permanently detach a job from the shell session, use the disown %job_number command.
6. You can also send a specific signal to a job using the kill %job_number command.
7. Remember, you can use the jobs command to see the status of all jobs in the current session.

To resume stopped Unix jobs, follow these steps:
1. Find the job number by running the command jobs -p. This will display a list of stopped processes along with their job numbers.
2. Use the command fg %job_number to bring the desired job to the foreground. For example, fg %1 will bring the job with job number 1 to the foreground.
3. If you want to run the job in the background instead, use the command bg %job_number. This will allow the job to continue running while you work on other tasks.
4. Alternatively, you can send a specific signal to a job using the kill %job_number command. This can be useful if you need to stop or terminate a job.
Remember, job control commands like jobs -p, fg %job_number, bg %job_number, and kill %job_number are essential for managing your Unix jobs efficiently.
