ICANN Considers Single Letter Domains

* * Beatles-Beatles writes "...as the Internet's key oversight agency considers lifting restrictions on the simplest of names. In response to requests by companies seeking to extend their brands, the Internet Corporation for Assigned Names and Numbers will chart a course for single-letter Web addresses as early as this weekend, when the ICANN board meets in Vancouver, British Columbia. Those names could start to appear next year."

Re:these are simple, just like unix!

And why is a shell builtin not a command?
For me, a command is something which I can type in a shell. It may execute a shell builtin, a shell function, an alias, or an executable found in the path, but in any case it's a command.

See e.g. the bash man page:

Simple Commands
              A simple command is a sequence of optional variable assignments fol-
              lowed by blank-separated words and redirections, and terminated by a
              control operator. The first word specifies the command to be executed,
              and is passed as argument zero. The remaining words are passed as
              arguments to the invoked command.

See, no mention that a command has to correspond to an executable.
It also has a section named "SHELL BUILTIN COMMANDS".

The fact that you cannot use sudo to issue a cd command is completely unrelated to that nomenclature (as is the fact that a csh may not be able to execute a bash builtin command). Note that even if sudo successfully executed the cd command (say, by executing it in a root subshell), the intended effect will not happen (because the directory change would only happen in the subshell - which immediatly terminates afterwards -, and the original shell's current directory will not be affected).

So before being pedantic, better first check you are right.
