如果您從程序中 ^Z，它會“停止”。怎麼轉回來？

我不小心“停止”了我的telnet過程。現在我既不能“切換回”它，也不能殺死它（它不會響應kill 92929，其中 92929 是程序 ID。）

所以，我的問題是，如果你在 linux 命令行上有一個停止的程序，你如何切換回它，或者殺死它，而不必求助於它kill -9？

最簡單的方法是執行將其帶到前台：fg

$ help fg
fg: fg [job_spec]
   Move job to the foreground.

   Place the job identified by JOB_SPEC in the foreground, making it the
   current job.  If JOB_SPEC is not present, the shell's notion of the
   current job is used.

   Exit Status:
   Status of command placed in foreground, or failure if an error occurs.

或者，您可以執行以使其在後台繼續執行：bg

$ help bg
bg: bg [job_spec ...]
   Move jobs to the background.

   Place the jobs identified by each JOB_SPEC in the background, as if they
   had been started with `&'.  If JOB_SPEC is not present, the shell's notion
   of the current job is used.

   Exit Status:
   Returns success unless job control is not enabled or an error occurs.

如果您剛剛點擊，那麼只需不帶參數Ctrl Z地執行即可恢復工作。fg
