So if you have admin privileges these days, that usually means that you’re allowed to use the “sudo” command. No, folks, it doesn’t rhyme with “pseudo”. The “root” account is also called the “super-user” because of its super powers and so “sudo” is literally “super-user do”. These days, though, the humble “sudo” command is the tool of choice: it lets you execute a single command as “root”. It used to be that Un*x system administrators would spend most of their time as normal users, logging into the “root” account only when necessary, and then logging out again. (Note for the Un*x-impaired: this deletes all of the files on your disk, and is generally considered to be a bad idea.) See, on Un*x-family systems, there are really only two levels of privilege: either you’re a normal users, and there are some things you just can’t do, or you are the “root” user, and you can do anything you like-including going to the root of the file system and entering “rm -rf *” on the command line. (And if you’re a working programmer, and you’re forced to use a Windows machine on which you don’t have admin privileges, why aren’t you looking for a new job?)īut on Linux or Mac OSX, “admin” privileges mostly give you access to the ever dreaded, much to be feared “sudo” command. On Windows you just need “admin” privileges, and then there’s no problem. When you install ActiveTcl, it naturally wants to be installed for all users on the machine.
