This is not 100% true. As Neil Bothwick said, *the same program* can
behave differently based on the name it was invoked with, so [ could
very well have been implemented as a link to test (or viceversa), but
this is not the case, as you can see with a
ls -l /usr/bin/test /usr/bin/[
Um, no.
Uhm, *YES*.
Read my post again.
You better do so.
The command 'test' and the command '[' have
*different* syntax
Yes.
so cannot possible be links to each other
Why not?
The command does behave differently depending on the name
it is called with, but this does not change the syntax used on the
command line that invokes it.
What are you talking about?
Of course the program could have a different syntax.
For example, compare the syntax that zipinfo and unzip have.
