How do I export/dump mongodb database?

Question

I tried a mongo export like this:

./mongodump --db local --collection lecturer 

and then I tried:

./mongodump --db  local -         


        

Answer 1

mongodump is a command-line utility and it's supposed to be run from the system command prompt, not the mongo javascript shell.

./mongodump --db local --collection lecturer

if successful, this command will create some files under dump directory in the current dir.
