set volume in max os x terminal

Costing my much time to search, It seems no command for setting volume in Leopard. When I used AppleScript to do this, I didn't know why the executable file cause some problem in screen. But Ruby's applescript gem do this good. I saved below content as /usr/bin/volume, and then I could use $ volume [1-7 as volume] to set Leopard's Volume from remote.

01 #!/usr/bin/env ruby
02
03 require 'rubygems'
04 require 'applescript'
05
06 AppleScript.execute("set volume #{ARGV[0]}")


update 2008/8/3

the way using applescript interpreter is $ osascript -e "set volume [1-7]"
or call in script by shebang.

01 #!/usr/bin/osascript
02
03 set volume [1-7]

 10     "te" using 2:11 title "band 5" with linespoints, \

ruby readline

loop do
    line = Readline::readline("app shell> ")
    if line
        Readline::HISTORY.push line
        puts line
    else
        puts
        break
    end
end

This is a the most basic usage.
I want to find a way could act as irssi :/

 

欄

多愁善感 淌 一點點

青春歲月 落 一片片

彷彿存在母體操縱的世界

深深地難以自拔

於沒有方向的原點

燈火玲瓏處

憑欄人

獨倚

何是回首時

天守閣之徘

當王牌已然從天而降

剩下的也只剩下祈求上蒼

天守閣的銅牆鐵壁阿

且看我是否是那德川家康

夜月,燈火,今夜亦瘋狂
