[General] screen command or a replacement

[Abdulaziz AL-Asfour]

Salam Alaykom all..

Thanks to Bashar and Sabah..

I don't know why I thought losing a connection before pressing ^AD would cuz
also losing that session... maybe i did something wrong in the past... or
maybe there was a network problem causing both the screen and command
running beneath to stop as brother Sabah mentioned.

I just tested the following

   - screen commandhere

and

   - screen
   - Enter
   - command

All allowed me to resume the connection after manually closing the
terminal...

After having several tests..

I just tested it on a production server (which has a screen running the appz
) .... I have to admit it, I was kinda scared to lose the session .. but
al7amdollah the screen is back after "screen -r"....    :)

I also found the script command interesting :)

Thanks all for the feedback....

And it's nice to see the start of "technical questions" with quick
feedback..... I think it is much faster than linuxforum.com..

Lazim asawee da3ayah :)

See ya guyz tomorrow inshallah
