There are stopped jobs appears in Linux

Dealing with stopped jobs
Sometimes when you try to logout, you'll get a message saying there are "stopped jobs ". these stopped jobs are programs or processes which have been susponded by a ^ Z (CTRL-z) command. you have to either make the job active again, or get it running properly
In the "background" before you can logout.

Stopping a program is useful if you want to temporarily suspend working on one program so you can do something else.

To see a list of stopped jobs, type:

Jobs

You will see a list of the stopped programs. Here's an example showing a stopped "Learn" session:

[1] + stopped learn

You can kill this stopped job by typing:

Kill % 1 (Where % 1 is the number of the job To be killed>

Or you can make the program active again by typing:

FG % 1 (Where % 1 is the number of the job)

FG stands for foreground. (You are bringing the program from susponded status back to the foreground.) once brought back to the foreground, you can continue the program or quit in a normal manner.
