open -a /System/Library/CoreServices/Classic Startup.appMy default shell in the Terminal is bash, which supports aliases, so I have added the following line to my .profile:
alias classic='open -a /System/Library/CoreServices/Classic\ Startup.app'This way, I can start the Classic environment from the Terminal simply by typing classic.
[Editor's note: If you use the default tcsh shell, aliases are also supported (search the site on 'alias' for a few articles). The alias command in tcsh would look like alias classic 'open -a /System/Library/CoreServices/Classic\ Startup.app']
