RPIO 0.90 rpio, the command line tools
http://pythonhosted.org/RPIO/rpio_cmd.html#rpio-curses
rpio includes two command-line tools which allow you to inspect and manipulate GPIO’s system wide (including those used by other processes). The BCM GPIO numbering scheme is used by default.

rpio --inspect-all (or -I) is perhaps the most popular command, which shows you all gpios on the board, with function and state. Here is an overview of all the functions of rpio:
Show the help page:
$ rpio -h
Inspect the function and state of gpios (with -i/--inspect):
$ rpio -i 7
$ rpio -i 7,8,9
$ rpio -i 1-9
# Example output for `rpio -i 1-9` (non-existing are ommitted):
GPIO 2: ALT0 (1)
GPIO 3: ALT0 (1)
GPIO 4: INPUT (0)
GPIO 7: OUTPUT (0)
GPIO 8: INPUT (1)
GPIO 9: INPUT (0)
Inspect all GPIO's on this board (with -I/--inspect-all):
$ rpio -I
Set GPIO 7 output to `1` (or `0`) (with -s/--set):
$ rpio -s 7:1
You can only write to pins that have been set up as OUTPUT. You can
set this yourself with `--setoutput <gpio-id>`.
Wait for interrupt events on GPIOs (with -w/--wait_for_interrupts). You
can specify an edge (eg. `:rising`; default='both') as well as `:pullup`,
`:pulldown` or `pulloff`.
$ rpio -w 7
$ rpio -w 7:rising
$ rpio -w 7:falling:pullup
$ rpio -w 7:rising:pullup,17,18
$ rpio -w 1-9
Setup a pin as INPUT (optionally with software resistor):
$ rpio --setinput 7
$ rpio --setinput 7:pullup
$ rpio --setinput 7:pulldown
Setup a pin as OUTPUT (optionally with an initial value (0 or 1)):
$ rpio --setoutput 8
$ rpio --setoutput 8:1
Show Raspberry Pi system info:
$ rpio --sysinfo
# Example output:
000e: Model B, Revision 2.0, RAM: 256 MB, Maker: Sony
You can update the RPIO package to the latest version:
$ rpio --update-rpio
Install (and update) the rpio manpage:
$ rpio --update-man
$ man rpio
