mongodb:query:find
This command uses the mongo
command-line interface to execute a MongoDB shell command. The command is executed within the context of a specified MongoDB database.
Here is a step-by-step breakdown of the command:
-
mongo
: It is the command to run the MongoDB shell. -
--eval '<command>'
: This option allows you to specify a JavaScript command to be executed by the MongoDB shell. In this case, the command being executed is enclosed within single quotes and contains two placeholders (${collection}
and${json_query}
). -
db.${collection}.find(${json_query})
: This is the JavaScript command being executed. It performs a database query using thefind()
method on a specific collection. The values of${collection}
and${json_query}
are replaced with actual values at runtime.
-
${collection}
is a placeholder for the name of the collection you want to query. For example, if${collection}
is replaced with"users"
, it will search for documents in theusers
collection. -
${json_query}
is a placeholder for a JSON document that specifies the query criteria. It is passed to thefind()
method as an argument. For example, if${json_query}
is replaced with"{ name: 'John' }"
, it will search for documents where thename
field is equal to"John"
.
Overall, this command allows you to execute a MongoDB query from the command line by providing the collection and query criteria as arguments.
