How do i stop myself getting logged out of redbrick in res?

This happens after 2 hours automatically, for security as well as keeping the number of sessions on the system down. If you want to keep yourself logged in there is a script you can place in your home directory to reset your idle status every hour. First thing you have to do is make sure that your home directory is in your PATH. Add this line to your .zshrc file to do this.

PATH="$HOME:$PATH"

Then source your .zshrc file. Next thing to do is create the shell script. First of all we are going to open a file called noidle in our text editor.

nano ~/noidle

Next we are going to place the following code in it. Many thanks to Dizer for this code. You can cut and paste this part.

  1. !/bin/sh

echo "Starting no autologout script." while true #while true do touch `tty` #wake your tty sleep 3600 #wait 1 hour done #loop and do it again

Now close your file and save it. Now when you want to leave your computer unattended. just start this program by typing "~/noidle". When you want to come back and use your terminal you can just turn it off by using CTRL-C
