Pretty print in MongoDB shell as default

(Notice:The following answer should be a original version of the question, which did not have requirements for “default”)

The below code will be usefull:

db.collection.find().pretty()

Just you can try to add:

DBQuery.prototype._prettyShell = true

Here to your file in $HOME/.mongorc.js to enable pretty print globally by default

(Notice: For the following answer to the updated question)

Just can you do this on the CLI

echo DBQuery.prototype._prettyShell = true >> ~/.mongorc.js

It always provide pretty results
