I need to press space in two windows at least almost simultaneously to debug my own version of more util. When i'm writing something like

: at "#" stuff " "

it is working too long (delay about 3 seconds from "command from $USER" to real space pressing) Is it possible to do it faster?

So if i have 2 windows: my own more and GNU more I wish to press space and immediately see both more's reactions

  • I wonder if two separate at jobs would execute simultaneously-enough? – Jeff Schaller Apr 27 '16 at 12:44
  • +- second just for usability, but less than 3s – vladimirg Apr 27 '16 at 13:34
  • I tried screen -X at '#' stuff 'date +%S.%N\n' on my gnu screen version 4.03.01 and there was only about 2millisecs difference. – meuh Apr 27 '16 at 15:05
  • What about time between this command and 'date +%S.%N\n' execution? – vladimirg Apr 27 '16 at 15:39

msgwait 0 is an answer to my question


Well, i need to visual compare output from default more and my implementation. To make it faster i created session with msgwait 0, attached another terminal started new window with msgwait 0. After wait each time i calls

at "#" stuff " "

Both of them scrolls by one screen. It's all i need

Sorry for unclear question.

  • In what way is that an answer. Please elaborate – Anthon Apr 27 '16 at 18:04
