I am trying to make the desicion whether or not to get a linux computer. The thing that worrys me the most isn't instability or incompatibility (I bought a mac for those), but the command line. I'm quite shy of thing. I have dabbled in Mac's Terminal program and upon reading up I noticed that Linux is akwardly close to Mac OS X. I just wanted to know what the differences would be between the two. I mean if I could practice on my mac to determine whether I could use a linux, that would just be great. I guess since they are both built on UNIX, they share a great deal; however, I wanted to know what commands and aspects differ?
