To create a logged Screen session, use the following command: screen -L -S session-name Linux Screen Tips for Effective Usage Running tasks in isolated Terminals also simplifies the log data for easier troubleshooting and debugging. Disabling them also lets you reallocate server resources to run another hardware-intensive task. Since each task runs independently, you can terminate unresponsive ones without affecting other processes. This simplifies multitasking and improves process isolation and resource efficiency. You can create multiple Screen sessions and windows, each running a separate process. To improve VPS security, enable the Screen password by entering Ctrl-a + :password in the session. To do so, run the following commands sequentially: sudo apt install htop screen -r session-name htopĮnabling session sharing in Linux lets multiple users run commands in your server. To monitor the task in the virtual session, install and enable a process tracker tool like htop. For example, it allows your Linux Minecraft server to remain accessible after you quit the session. In addition to bash scripts, this feature keeps hosted applications active in the background. Alternatively, execute it via the main shell using the stuff command: screen -S session -X -p 0 stuff "cd /script/directory/path. To do so, create a new Screen session, run the script in the virtual Terminal, and detach from it. This feature is useful for executing bash scripts, which may take a long time to run. Screen keeps long-running processes in the background, allowing you to continue where you left off after disconnecting from the current SSH session. Rather, it will print error messages and bash script outputs. The virtual Screen session won’t produce an output if the command runs properly. For example, we’ll run the following command to echo a message in the hostinger session’s first Terminal window: screen -S hostinger -X -p 0 echo "Test message" Replace 0 with the Terminal window number. To do so, use this syntax: screen -S session-name-or-id -X -p 0 command Linux Screen lets you run commands to a detached session without reattaching and opening it. For example, you can run either Screen command to reattach to the ssion1 session: screen -r 1268 screen -r session1 Send Commands to a Detached Session Replace ID-name with the actual Screen session ID or name. To reattach to a running Screen session, run the following command in your main system Terminal: screen -r ID-name Terminal will output the following message, indicating you have returned to the original shell: For instance, use this Screen command to start a new session named session1: screen -S session1 If you don’t specify the session name, Screen will automatically set it as tty1.hostname.įor easier identification, give your session a custom name using the -S option. To start a session, enter the screen command and hit space to close the welcome message.
