Walkthroughs

Create start script

The agent finds the example script and reads its content, so it writes a new batch file with the required parameters and joins lines with a caret. It is ready. This valheim dedicated server setup uses glob and read_file to locate the template. write_file creates the new start script with the correct parameters for the server. Shell runs the script and checks the exit code for success immediately. Ask first mode shows the diff before you accept the changes made. You review the changes and confirm the script is ready to run now. The agent never touches the game client, and the server lags when player has connection issues.

Manage admin list

grep searches the server log for the player connect event and identifies the Steam ID of the new admin, so edit_file updates adminlist.txt with the new ID. Check the diff. The agent shows a diff of the changes in the chat card. You can approve the edit in Ask first mode before the changes are applied. Shell runs the start script to apply the changes immediately. This setup helps you run one server for different groups. The server is now ready for the new admin to join. The agent uses grep to search the log for player disconnects.
