You can do this without resort to an external process: |
| 6 |
IFS=- |
| 7 |
read _ _ spec _ <<< "$CHOST" |
| 8 |
unset IFS |
| 9 |
- or you can do: |
| 10 |
IFS=- |
| 11 |
arr=($CHOST) |
| 12 |
unset IFS |
| 13 |
spec=${arr[2]} |
| 14 |
- which is useful if you don't know how many elements there are. |
| 15 |
(IFS wouldn't affect the second assignment, but it's safest to unset it as |
| 16 |
soon as you've got whatever you needed with the non-default, ime.) |

Note that quoting is needed in the first one and will break the second one. |
| 19 |
In first instance the words are split before being read, and then the |
| 20 |
separator is not used at all, so first _ takes the whole line til the new |
| 21 |
line delimiter. In the second, it's the usual quote situation, so with |
| 22 |
quotes it's one parameter, without it's split according to IFS. |
