import - How do I export/dump mongodb database?

I tried a mongo export like this:

./mongodump --db local --collection lecturer 

and then I tried:

./mongodump --db  local --collection posts --out - >  lecturer .csv  

and I get the same error message: Syntax Error: syntax error (shell):1

  1. What's wrong with my code?
  2. Where is the data stored if export successfully?

How to backup and restore databases

Start Mongo, open a new tab in terminal. First navigate to the folder where you want to save the backup, then type the following command.

Backup single database:

mongodump --host localhost --port 27017 --db db_name

Restore single database:

mongorestore --host localhost --port 27017 --db **** dump/db_name

(In this case, **** represents UserDefinedName for the database > mydb dump/db_name > this will import dump db into mydb)

Backup all databases:

mongodump --host localhost --port 27017

Restore all databases:

mongorestore --host localhost --port 27017  dump
