I want to automatically logout user from the login shell after defined period of inactivity, but leave X Window Terminals untouched. This will allow me to enhance security a little bit, as I will not accidentally leave superuser session running for a long period of time.
The proper way to achieve this is to set
TMOUT variable to the number of seconds to wait for an user input using global profile.
long running process) and it will be not terminated.
Execute following commands to define
120 seconds timeout.
$ cat << EOF | sudo tee /etc/profile.d/tmout.sh # Execute only outside of X-terminal [ -z "\$DISPLAY" ] || return 0 export TMOUT=120 EOF
$ sudo chmod 644 /etc/profile.d/tmout.sh
Changes will take place after user re-login. Bash will simply terminate after timeout.
