Well, thenicepartwithSudoiswhathappensisifyouwanttodospecificthingslikethingsthatwillreallymodifytheoperatoroperatingsystem, youhavetouse a pseudocommand.

But I'm notgoingtogointothattoday.
I thinkthat's a littlebitmoreadvanced.
Now, when I thinkofSue, doonethingtothinkaboutthismightbe a littlebitof a lion.
Is, um, thisshowsmyageandagain, oneoftheissuesthatyou'regonnarunintointheLenoxworld.
Sowhen I thinkofpseudoandwhenever I talkaboutitgoinginthefuture, I thinkofitasSuperuserdoSo.
SuperUserisbasicallythatrouteaccount.
SuperUseristhesameasrudeaccount, essentially, sothat's that's how I thinkaboutright.
I thinkaboutit.
I'm atmypermissionlevelandthen I needtodosomethingthat I don't havetheauthorityto.
D'oh!
So I saySuperuserSuedosuperuserdointhewhateverdoesn't want?
Andbasicallythat's how I thinkaboutanescalator, apparentlynow, though, tobeclear, I thinkthey'renowcallitSubstituteuserdobecauseyouknowLennoxWorld, he's notreallysuperuser.
You'rereallysubstitutingusers.
Soifyousaysuperuser, it's wrong.
It's reallysubstance.
Soagain, justoneofthethings I thinkaboutwithwordsandallyISMs, and I'vebeendoingthissolongithurts.

I thinksuperuserdomakes a lotofsense, I thinkSuperuserdoSueDio.
Yes, Okay, I gotit.
