List processes running inside of screen (manager with with VT100/ANSI terminal emulation)

gnu-screenprocess

I have an application that during installation runs a bunch of processes via screen, so I can see those if attached to the screen, however I don't see those via "ps -ef" or "ps auxww". How can I list all the processes running inside of screen ?

Thanks.

start cmd: # screen -ls
There is a screen on:
        24525.pts-0.syscontrol  (Attached)
start cmd: # pstree -p 24525
screen(24525)─┬─bash(10773)───su(10790)───bash(10791)
              ├─bash(10863)───pstree(11099)
              └─bash(24526)

GNU Screen – Share Terminal with Multiple Users

Yes, you can do it with screen which has multiuser support.

First, create a new session:

screen -d -m -S multisession

Attach to it:

screen -r multisession

Turn on multiuser support:

Press Ctrl-a and type (NOTE: Ctrl+a is needed just before each single command, i.e. twice here)

:multiuser on
:acladd USER ← use username of user you want to give access to your screen

Now, Ctrl-a d and list the sessions:

$ screen -ls
There is a screen on:
    4791.multisession   (Multi, detached)

You now have a multiuser screen session. Give the name multisession to acl'd user, so he can attach to it:

screen -x youruser/multisession

And that's it.

The only drawback is that screen must run as suid root. But as far as I know is the default, normal situation.

Another option is to do screen -S $screen_id -X multiuser on, screen -S $screen_id -X acladd authorized_user

Hope this helps.

Bash – list graphical processes from terminal

Try xrestop or xrestop -b.

It is intended to measure how many X resources each X window consumes, but as a small bonus identifies name of the windows and corresponding PIDs.
