db.foo.find().limit(300)
won't do it. It still prints out only 20 documents.
db.foo.find().toArray()
db.foo.find().forEach(printjson)
will both print out very expanded view of each document instead of the 1-line version for find():
How to print out more than 20 items (documents) in MongoDB's shell?

With newer version of mongo shell (mongosh) use following syntax:
config.set("displayBatchSize", 300)
instead of depreciated:
DBQuery.shellBatchSize = 300
Future find() or aggregate() operations will only return 300 documents per cursor iteration.
I suggest you to have a ~/.mongorc.js file so you do not have to set the default size everytime.
# execute in your terminal
touch ~/.mongorc.js
echo 'DBQuery.shellBatchSize = 100;' > ~/.mongorc.js
# add one more line to always prettyprint the ouput
echo 'DBQuery.prototype._prettyShell = true; ' >> ~/.mongorc.js
To know more about what else you can do, I suggest you to look at this article: http://mo.github.io/2017/01/22/mongo-db-tips-and-tricks.html
show dbs
use your database name
in my case, I'm using - use smartbank
then - show collections - just to check the document collections name.
and finally, db. your collection name.find() or find({}) -
show dbs
use smartbank
show collections
db.users.find() or db.users.find({}) or db.users.find({_id: ObjectId("60c8823cbe9c1c21604f642b")}) or db.users.find({}).limit(20)
you can specify _id:ObjectId(write the document id here) to get the single document
or you can specify limit - db.users.find({}).limit(20)
