|
| 26 |
| **list** [--no-headers] [--separator=*SEPARATOR*] |
| 27 |
| [-o *[+]FIELD,...*] [group...] |
| 28 |
|
| 29 |
Lists all existing node groups in the cluster. |
| 30 |
|
| 31 |
The ``--no-headers`` option will skip the initial header line. The |
| 32 |
``--separator`` option takes an argument which denotes what will be |
| 33 |
used between the output fields. Both these options are to help |
| 34 |
scripting. |
| 35 |
|
| 36 |
The ``-o`` option takes a comma-separated list of output fields. |
| 37 |
If the value of the option starts with the character ``+``, the new |
| 38 |
fields will be added to the default list. This allows to quickly |
| 39 |
see the default list plus a few other fields, instead of retyping |
| 40 |
the entire list of fields. |
