Um, no. Read my post again. The command 'test' and the command '[' have |
| 14 |
*different* syntax so cannot possible be links to each other and still |
| 15 |
have it work. The command does behave differently depending on the name |
| 16 |
it is called with, but this does not change the syntax used on the |
| 17 |
command line that invokes it. |
