Hi I have a Ti DVI 667/512/30, running 10.2.4. I never messed with Terminal until just now. I wanted to see my uptime, so I launched and, at the prompt, typed uptime. It tells me command not found. Same for cal (got these 2 from The Missing Manual). If I type ls ~ i do get the contents of my home folder. I looked at some of the old threads about uptime and saw the pics people posted. My Terminal window looks the same except it doesn't say 'Welcome to Darwin.' Any ideas on what's wrong?
