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  run-
       ning, independent of the setting of the AUTO_CONTINUE option.
