mongoexport:tldr:5178f
The command "mongoexport" is used to export data from a MongoDB collection into various formats, such as JSON or CSV.
In this specific command, the options are as follows:
--collection=${collection_name}: This specifies the name of the collection from which the data will be exported. The value of ${collection_name} should be replaced with the actual name of the desired collection.
--jsonArray: This option indicates that the exported data should be formatted as a JSON array. By default, each document is stored in a separate JSON object. However, using this option combines all the documents into a single JSON array.
So when you run the command "mongoexport --collection=${collection_name} --jsonArray", it will export the data from the specified collection in a JSON format, with all the documents combined into a JSON array.
