Finding Mac OS X version from command line
To display Mac OS X operating system version information use sw_vars command. Open the Terminal and type the following command:
Say hello to 'say' command line tool
say is command line tool. It uses the Speech Synthesis manager to convert input text to audible speech and either play it through the sound output device chosen in System Preferences or save it to an AIFF file. Open the Terminal and type the following command:
say "Mac OS X" say "Mac OS X .8.4"
The following command uses sw_vers as bash command line substitute to find out the current version and pronounce it using the say command:
