    MongoDB version manager


    $ npm install -g m


    $ git clone git:// && cd m && make install

    Installing Binaries

    Install a few versions, the version given becomes the active mongodb binary once installation is complete.

    $ m 2.0.7
    $ m 2.2.0-rc2

    List installed binaries:

    $ m
    ο 2.0.7

    Use or install the latest official release:

    $ m latest

    Use or install the stable official release:

    $ m stable

    Install a custom or patched version of mongodb from a tarball:

    $ m custom 2.1.2-me

    Install a version of mongodb from source (requires scons):

    $ m 2.2.3-rc0 source

    Install an enterprise release

    $ m 3.2.8-ent

    Removing Binaries

    Remove some versions:

    $ m rm 2.2.0-rc1 2.0.4 2.4.0-rc0 3.2.8-ent

    Note that you cannot remove the actively running version. Change to a different version before removing.

    Binary Usage

    When running multiple versions of mongodb, we can target them directly by asking m for the binary path:

    $ m bin 2.0.7

    Start up mongod 2.0.7 regardless of the active version:

    $ m use 2.0.7 --port 29000 --dbpath /data/2.0.7/

    Execute a script with the 2.0.7 shell regardless of the active version:

    $ m shell 2.0.7 some.js

    with flags:

    $ m s 2.0.7 --port 29000 --eval 1+1

    When installing or changing the active version we might want to run custom scripts:

    $ m pre install /path/to/my/script
    $ m post install /path/to/script
    $ m pre change /path/to/my/script
    $ m post change /path/to/script

    Multiple scripts may be added for any event. To add two pre change scripts:

    $ m pre change /path/to/script1
    $ m pre change /path/to/script2

    Scripts are executed in the order they were added.

    List all pre change hooks:

    $ m pre change

    List all post install hooks:

    $ m post install

    To remove a post install hook:

    $ m post install rm /path/to/scriptB

    Remove all post install hooks:

    $ m post install rm

    m by default installs mongodb to /usr/local/m/versions, from which it can see what you have currently installed, and activate previously installed versions of mongodb when m <version> is invoked again.

    Activated mongodb versions are then installed to the prefix /usr/local, which may be altered via the M_PREFIX environment variable.

    To alter where m operates simply export M_PREFIX to whatever you prefer.




    Yes tj, this is nearly identical to n. Huge thanks!
