OPTIONS
*
marks required options.
Common options
- --format=s
-
Choose output format, e.g. json, text.
Default value:
undef
- --help, -h, -?
-
Display help message and exit.
- --json
-
Set output format to json.
- --naked-res
-
When outputing as JSON, strip result envelope.
Default value:
0
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
[200,"OK",[1,2,3],{"func.extra"=>4}]
The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:
[1,2,3]
- --page-result
-
Filter output through a pager.
- --subcommands
-
List available subcommands.
- --version, -v
-
Display program's version and exit.
- --view-result

View output using a viewer.
