I run mongo --help and it has an options for evaluate javascript.
mongo --eval arg
However, I haven't found any example of how to use it. I try to run it but with no success. anyone know how to do it?
the reason is that, I want to delete a collection through mand line ( so that I can reuse the code and put it into shell script). I know I can write another nodejs and call the db to run it.. but instead of 20 lines of code, it would be nice if there is a solution with only few lines and be faster. :)

Reset to default 9That would be:
mongo <server>:<port>/<database> --eval "db.<some_collection>.drop();"
Or if you want to do something in more lines you can call a file (must end with .js):
mongo <server>:<port>/<database> some_instructions.js
