linux fg command

When you run a job in background, you can bring it to foreground by command fg
Example:
—————–
./test &
fg 1
—————–
Then the job “test” would be in foreground now.
fg [%job_id], job_id specifies the job that you want to run in the foreground and 1 means most recently background job.
This command is useful when you don’t want to open new terminal to issue some other command, you can now do this in same window by putting one job in the background and pulling back it after issuing another command.
