Run Linux Commands on BeagleBone Black Hardware

Use the system function to run Linux® commands on the BeagleBone Black hardware. Pass commands, such as 'ls -al', as the second argument. The function returns standard output from the Linux command line.

system(bbb,'ls -al')

Use the openShell function to open an SSH PuTTY terminal that is connected to the Linux command-line interface on the BeagleBone Black hardware. Log in as the root user. By default, the root user login does not require a password.

bbb = beaglebone()
openShell(bbb)

It is a good security practice to set the root user password. Use the PuTTY terminal to run the passwd command.

passwd

Follow the prompts and change your password.

After changing the password, clear the bbb object and any objects that you created using bbb. Then, use beaglebone to create a new connection based on the new password.

clear bbb
bbb = beaglebone('172.28.201.137', 'bbb','newpassword')
