disown [ job ... ]
job ... &|
job ... &!
       Remove the specified jobs from the job table; the shell will no
       longer report their status, and will not complain if you try to
       exit an interactive shell with them running or stopped.  If no job
       is specified, disown the current job.

       If the jobs are currently stopped and the AUTO_CONTINUE option is
       not set, a warning is printed containing information about how to
       make them running after they have been disowned.  If one of the
       latter two forms is used, the jobs will automatically be made
       running, independent of the setting of the AUTO_CONTINUE option.
