SdTerminal

Basic terminal interface for Arduino SD card logging/file management. Allows basic file management of an SD card with an Arduino through serial commands.

Commands:

ls -- List all files on SD card
rm all -- Delete all files on SD card except for the file currently being used for datalogging
rm <filename> -- Delete the specified file on the SD card except for the file currently being used for datalogging
<filename> -- Display the entire contents of the file

Notes:

The returned message ? signifies the last command was invalid
