Another jaw-dropping feature of Mac OS X when showing off to your friends – open the Terminal (~/Applications/Utilities/Terminal ) and type say command, followed by any text.

For example type: say I like silvermac and press return. Your computer promptly does what you asked it do do, it says I like silvermac.
[tags]OSX, terminal, cool, say[/tags]
Some commands to show off:
uname -a | say
uptime | say
Have fun! :D
Nice! I’ve only had my macbook pro for a couple weeks. But each day I find out something I couldn’t do in windows very easily. Mac forever!
Basicly… ‘echo’ with minus one letter.
@Mailman: I do not have a Mac, so I cannot test this, but I think by “say”, they mean the computer physically puts the text in to speech (as OS X does have builh in text-to-speech support), and “says” it, through speakers. I do have a PC running Windows, though, and all “echo” does, is repeat back what you tell it to – in text.
you can also do this in script editor.
type:
say “words”
and press compile button at top then run, you can also tell it to beep,
beep 3
tells it to beep 3 times, you can change the beep in:
system prefrences/sound/sound effects
