Mongo: get all results to file instead of page iteration

http://www.mongodb.org/display/DOCS/Scripting+the+shell
paragraph "Differences between scripted and interactive / Printing".

connect to host:
./mongo server.com/mydb
> db.users.find()


to do the same from shell:

./mongo server.com/mydb --quiet --eval "db.users.find().forEach(printjson);" > 1.txt

Attention: for prefix ".forEach(printjson);" without it you will get error like
DBQuery: mydb.users-> undefined
