  See also the `jobs` command.
  More information: https://www.gnu.org/software/bash/manual/bash.html#index-disown.

  - Disown the current job:
    disown

  - Disown a specific job:
    disown %job_number

  - Disown all jobs:
    disown -a

  - Keep job (do not disown it), but mark it so that no future SIGHUP is received on shell exit:
    disown -h %job_number
