Re: What is the '[' binary?

[Alfred M. Szmidt]

   Just curious. It shows as a binary in the README and the
   installation directory.

It is the `test' binary.  For example:

if [ $foo -eq $bar ]; then ...

and

if test $foo -eq $bar; then ...

are equal.  It was/is used on systems that don't have `[' as a builtin
I think.

Cheers.
