General Notes on Plan 9 Usage:


o System shutdown can be achieve with:

      disk/kfscmd halt

o IDE devices:

  sdC0 - Primary master IDE device
  sdC1 - Primary slave IDE device
  sdD0 - Secondary master IDE device
  sdD1 - Secondary slave IDE device

o Equivalent or similar commands in UN*X.

BASIC COMMANDS, Etc.

o Mounting floppy disks, CDROMs, etc.

    - Mount floppy:

      term% a:   (this toggles mount/unmount of floppy on /n/a:)

    - Mount FAT partition--where the loader and plan9.ini lives:

      term% 9fat:   (mounts on /n/9fat)  

    - Mount CDROM drive:

      term% 9660srv
      term% mount /srv/9660 /n/tapefs /dev/sdDO/data
        (Substitute your device for sdD0; CDROM will be mounted on
         /n/tapefs.)



PROBLEMS, SOLUTION, Q&A, and STUFF, Etc.:

 o How to issue something like ^C or ^D to stop a process at the
   command line.

    Solution: The Delete key will abort process launched at command
    line.

 o df equivalent command

    Solution: There is an rc script available for this.

 o how to read p9 troff docs located in /sys/doc/

    Solution: The files can be output using troff with -ms
    macros. Most are located in /sys/doc/ as *.ms and *.ps

 o ping, traceroute, and others seem to be missing.

    Solution: ip/ping, ip/ipconfig, ip/traceroute will execute these
    commands. Look in /bin/ip/ for more commands.

 o Have trouble with ISA NICs. The system panics and dumps to the
   screen. I don't know; need to figure this out.

    Solution: PCI NICs, especially NE2000 clones, seem to work.

 o What is /rc/bin/services/tcp564 

   Linux /etc/services refers to this as "plan 9 file service". What
   it's used for on Linux I couldn't say.

USING RIO:

 1. Right mouse button on root window (grey background) brings up menu:

    New - create a new window. Click and drag with right mouse
    button.

    Resize - not necessary to pick on menu. Left click and drag edge
    or corner of window.

    Move - not necessary to pick on menu. Right click on edge of
    window and drag to where you want.

    Delete - will kill a window.

    Hide - hide a window. To recover it Right mouse click and pick
    the window you want from the menu.

 2. Middle mouse button on root window brings up menu:

    Snarf - copy text to clipboard. Highlight text by dragging with
    left mouse button. Then middle mouse button and pick Snarf.

    Cut - cut text to clipboard.

    Paste - paste text from cut or snarf at position of cursor


USEFUL APPS ETC.

 1. sam - text editor   

 2. acme - very cool programmer's environment. A mouse lovers
    replacement for emacs. (Check out Wily if you want an acme clone
    for Linux.)

    acme mouse usage:

	 Note: 1, 2, and 3 are Left, Middle, and Right mouse buttons
	 respectively.

	 select - 1 sweep text
	 execute - 2 on single word; 2 sweep multiple words
       view file or change directory - 3 or 3 sweep
	 snarf - execute from menu
	 cut - 1 sweep then chord with 2
	 paste - chord 1+3
	 replace - snarf or cut something then select and paste the
		snarfed text
       toggle fonts - Type in the command "Font" then execute it.

 3. ftpfs - "mounts" ftp system as a filesystem on Plan9. You can
    then access it as if it were a part of the local namespace using
    the commands ls, cp, etc. instead of the ftp specific commands.
    You can also edit remote files--mounted as ftpfs--with acme or
    sam.  Ftpfs mounts are only necessary when the remote host is
    not a Plan 9 system; Plan9 to Plan9 systems have no need for ftp
    or nfs.

    ftpfs [ -/dqn ] [-k] -m mountpoint ] [ -a password ] [ -e ext ]
        [ -o os ] [ -r remoteroot ] system
