These are the default 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
- 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.
Advanced commands:
- stop-default: kills pd and jack
- disable-flash-writes: makes board boot up in a way that data is not written to the memory on next boot
- enable-flash-writes: re-enables the default state where card does allow data to be written to memory on next boot
- ~on-startup/load_default patch: on boot, system attempts to run this file automatically if it exists
- set-DNS-server <ip address>: sets DNS server
- sudo apt-cache pkgnames: List all of the Ubuntu packages available for install via the Internet.
- sudo apt-cache pkgnames | grep <word>: List only the available Ubuntu packages containing word.
