Run Linux Commands on Raspberry Pi Hardware

Note

Certain Linux^® functions are limited in MATLAB^® Online™. See Security Considerations for Raspberry Pi in MATLAB Online for details.

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

system(mypi,'ls -al')

Use the openShell function to open an SSH terminal that is connected to the Linux command-line interface on the Raspberry Pi hardware. Log in as the pi user. The default password for pi is raspberry.

mypi = raspi()
openShell(mypi)

It is a good security practice to change the default password. Use the SSH terminal window to run the raspi-config utility.

sudo raspi-config

Select 2 Change User Password and change the password.

After changing the password, clear the mypi handle and any handles that you created using mypi. Then, use raspi to create a new connection based on the new password.

clear mypi
mypi = raspi('172.28.201.137','pi','newpassword')
