bash quiz

ok, I just came across the coolest thing ever... it's actually really inane, but I find it funny when you find out things like this.

so I give it to you in the form of a quiz:

tell me why

$ if test -f /etc/rc.conf

and

$ if [ -f /etc/rc.conf]

are 100% identical.

I'll give you a hint: the only bash builtin is the "if"

isnt '[' is linked to 'test' thus its actually same thing? i am no bash coder so....

yup... it's funny that "[" is a symlink to test.... I saw that file sitting there today...

actually [ and test are bash builtins

 # type test
test is a shell builtin

but /usr/bin/test and /usr/bin/[ may be used if you rely on another simpler shell (ash, ...)
