Run Linux Commands on Raspberry Pi Hardware in MATLABOnline
You can run the ls command on the
Raspberry Pi hardware when connected to it from MATLAB
Online. Other Linux commands are not supported. To use your hardware from MATLAB
Online, follow the instructions in Connect to Raspberry Pi Hardware Board in MATLAB Online.
When connected to your hardware from MATLAB
Online, the default working directory is
/home/matlabrpi, instead of
/home/pi. Use ls to list the
contents of this folder. You can append any of the ls
command flags to display more information about the files. In this example,
the -al option lists the long format and includes hidden
files.
