is there a way to open/attach to all detached screen sessions on linux in one command/script? typically I have the following flow to open a session:
#see all screen sessions screen -rD #attach to one screen session screen -rD screen_name
It would be easier to have only one screen session with many terminals within. You create a new terminal with Ctrl+a+c, then you switch through them with Ctrl+a+<space> or <backspace> or a number.
I don't think there is an easier way if you do that manually. If you spawn sessions with a script, you may try using -X to make screen open a new window in an existing session and execute commands in there. Perhaps this answer is close to what you would need. You will need to make sure you name your screen session in a way, you can reference it later unambiguously.
