How to change mongoshell prompt?

I've recently re-installed Mongodb switching from the enterprise to the community version. Nevertheless, when I start mongo, this is the prompt format I get:

MongoDB Enterprise >

How can I change it to the standard prompt version? (i.e., > if I am not wrong)

Solution

  • You can change the prompt from within a shell session by setting the prompt variable. For example, issuing the following command within a Mongo shell ...

    var prompt="this_prompt >"

    ... will result in the shell's prompt changing to:

    this_prompt >

    You can change the default prompt for all future sessions by updating your .mongorc.js (you'll find this in your $HOME directory and if it does not exist then just create it). The following addition to your .mongorc.js ...

    var prompt=function() {
    return ISODate().toLocaleTimeString() + " > ";
}

    ... will result in this prompt:

    :~/dev/tools/mongodb/mongodb-osx-x86_64-3.4.7/bin$ ./mongo
MongoDB shell version v3.4.7
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.7
16:09:43 >
16:09:57 >

    Or, to get this prompt: > just add the following to your .mongorc.js:

    var prompt=">"

    There remains the sub text to your question, namely; where is the existing MongoDB Enterprise > prompt coming from?. It's hard to say but ...

    • Perhaps you have a Global mongorc.js; have a look in /etc/mongorc.js if you are on a *nix system or %ProgramData%\MongoDB if you are on Windows
    • Mongo behavour when finding a rc file is also subject to environment variables, more details in the docs.
