“`
# Connect to the remote device
connect 192.168.1.100
# Log in to the device
login user password
# Run a command
send “ls -l”
# Log out of the device
exit
“`
This script demonstrates the basic syntax of the Tera Term scripting language. By using a combination of commands and functions, you can create complex scripts that automate a wide range of tasks.
