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.
