Useful Commands for Satellite CCRMA

These are the basic commands you should use with Satellite CCMRA:

• ssh -XY ccrma@192.168.105.106: This logs into the Satellite CCRMA at the IP address 192.168.105.106 as the user ccrma, and with X window forwarding enabled.
• start-jackd: Starts the audio connection server. (More about jack at [1])
• pd &: Starts pd (More about pd at [2])
• sudo halt: Starts the shutdown process. Wait 20 seconds after this and then pull the power plug.

This is a list of commands that are useful to use on the Satellite CCRMA:

• pkill <name of program>: kills all instances of the program with that name. For example, pkill pd will stop pd if it is stuck or frozen somehow.
• sudo reboot: Reboot the system.
• <name of program> &: runs program as a background process, so that you can continue to type other commands into the console. For example, "arduino &" starts the Arduino IDE but also allows you to type other commands before you quit the Arudino IDE program.
• top: program that shows the CPU usage of the Beagleboard. Press 'q' to quit.
• alsamixer: lets you look at the mix of the audio input and output. Useful for setting the audio input level on the microphone, for instance.
• ls: lists the files in the current directory.
• ls <target>: lists the files in the target directory.
• cd <dir name>: changes the current directory. For example, 'cd ..' moves to the directory above the current directory.
• mv <source> <destination>: move file from source to destination
• pwd: lists the full path name of the current directory
• nano: opens a text editor
• cp <source> <destination>: allows you to copy files locally within the Beagleboard filesystem.
• sudo <command>: executes the command as a superuser once password is entered. For example, to stop the Satellite CCRMA before shutting down, type 'sudo halt'.
• df: displays free disk space.
• man <command>: show the manual for a command.
