$() is more consistent with other syntax elements in bash, It's essentially |
| 12 |
the same thing as evaluating a variable and inserting it's value. The `` |
| 13 |
syntax is a wild anachronism from days long ago that is completely at odds |
| 14 |
with everything else in the shell. Well, you can say that about many things in |
| 15 |
bash, but that's not a good reason to not fix anything... |

IIRC correctly it's not really deprecated either - that implies the thing will |
| 18 |
go away some time. It's more "strongly advised not to use it" |

Ummm, not having to look for it and find it first before pressing it? How |
| 24 |
about a keyboard that doesn't have it at all? |
