[SLUG] ask wake up by PID

["henry" <henry@xxxxxxxxxxxxxx>]

Dear List :

 

    I use "Ctrl-z" to let emacs sleep.

Then I use "fg" to wake it up.

 

 

Now I  open emacs & make it sleep ,I  open emacs & make it sleep ,I  open emacs & make it sleep .

( pls forgive me , English is not my native language .)

How could I wake up any of them by their PID ?   (I see their PID  by using "ps -A")

 

 

BestRegards'

Henry
