Error with MLCP copy syntax

I am using the following command

mlcp.sh copy -input_host localhost -output_host localhost \
-input_database emh-entity-manager-content \
-output_database emh-schema-map-manager-content \
-input_port 8000 -input_username admin -input_password xxxxxx \
-document_selector '/envelope[descendant::*:CustomerID = "SEVES"]'

And am getting the error

ERROR contentpump.ContentPump: Unrecognized argument: =

   [-copy_collections <true,false>] [-copy_permissions <true,false>]

   [-tolerate_errors <tolerate errors>] [-transaction_size <number>]
   [-transform_function <String>] [-transform_module <String>]
   [-transform_namespace <String>] [-transform_param <String>]

The error message is pretty much useless. I am trying to copy a set of files that match a specific xpath from one database to another on the same server.

What am I missing?

Thanks, Loren

Solution

There are a few things going on:

You are missing the output_username
You are missing the output_password
You are running across some sort of command-line escaping issue.

MLCP has a nice option called -options_file that helps take care of the command line escaping. You simply add all options to a file and that gets parsed instead. https://docs.marklogic.com/guide/mlcp/intro#id_36150

The command I would use is:

/path/to/mlcp.sh -options_file options.txt

With the content of the options.txt file being:

copy
-input_host
localhost
-output_host
localhost
-input_database
emh-entity-manager-content
-output_database
emh-schema-map-manager-content
-input_port
8000
-input_username
admin
-input_password
xxxxxx
-output_username
admin
-output_password
xxxxxx
-document_selector
/envelope[descendant::*:CustomerID = "SEVES"]
