m
MongoDB version manager
Installation
m is a bash script which can be installed & updated via npm for convenience:
$ npm install -g m
or installed by cloning the GitHub repo and running make install:
$ git clone git://github.com/aheckmann/m.git && cd m && make install
or fetched via wget and copied to a location of your choice:
$ wget https://raw.githubusercontent.com/aheckmann/m/master/bin/m && chmod +x ./m
Downloading MongoDB Binaries
Specify a MongoDB server version to try download a binary package (if available for your current O/S) or switch to a previously downloaded copy. After m successfully downloads or switches to a specified version of MongoDB, those binaries will become the default in the install path (typically /usr/local/bin/; see Details below for more information).
$ m 3.2.16
$ m 3.4.9
You can also specify a release series to download the latest available revision:
$ m 3.6
$ m 4.0
List installed binaries:
$ m
3.2.16
ο 3.4.9
3.6.0-rc1
Use or download the latest official release:
$ m latest
Use or download the stable official release:
$ m stable
Check what the latest available release is:
$ m --latest
$ m --latest 3.6
Check what the current stable release is:
$ m --stable
$ m --stable 3.6
Download a custom or patched version of MongoDB from a tarball:
$ m custom 3.5.13-me https://github.com/mongodb/mongo/tarball/r3.5.13
Download and build a version of MongoDB from source (NOTE: assumes build requirements are installed):
$ m 3.6.5 source
Download an Enterprise release:
$ m 3.4.9-ent
Select a MongoDB version without prompting for confirmation if a download is required:
$ yes | m 4.0.0
Removing Binaries
Remove some previously installed versions:
$ m rm 3.2.16 3.5.13-me
Binary Usage
Multiple versions of MongoDB can be downloaded and targeted directly.
Ask m for the binary path for a specific version that has already been downloaded:
$ m bin 3.4.9
/usr/local/m/versions/3.4.9/bin/
Ask m for the binary path for the latest revision of a release already downloaded:
$ m bin 3.6
/usr/local/m/versions/3.6.5/bin/
Start up mongod 3.4.9 regardless of the active version:
$ m use 3.4.9 --port 29000 --dbpath /data/3.4.9/
Execute a script with the 3.4.9 mongo shell regardless of the active version:
$ m shell 3.4.9 some.js
Execute a script with a 3.4.9 mongo shell and some additional flags:
$ m shell 3.4.9 --port 29000 --norc
When installing or changing the active version you 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
/path/to/script1
/path/to/script2
List all post install hooks:
$ m post install
/path/to/scriptA
/path/to/scriptB
/path/to/scriptC
To remove a post install hook:
$ m post install rm /path/to/scriptB
To remove all post install hooks:
$ m post install rm

Details
By default m downloads MongoDB binaries to /usr/local/m/versions in subdirectories named after the release version (3.2.16, 3.4.9, ...). Activated MongoDB binaries are symlinked into the bin directory in /usr/local. To alter where m operates, export the M_PREFIX environment variable with your preferred path prefix.
Previously downloaded versions of MongoDB can be activated using m <version> or
selected using of the variations in the Binary Usage section above.
