Minio Client Quickstart Guide

Minio Client (mc) provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage service (AWS Signature v2 and v4).

ls            List files and folders.
mb            Make a bucket or folder.
cat           Display contents of a file.
pipe          Write contents of stdin to target. When no target is specified, it writes to stdout.
share         Generate URL for sharing.
cp            Copy one or more objects to a target.
mirror        Mirror folders recursively from a single source to single destination.
diff          Compute differences between two folders.
rm            Remove file or bucket [WARNING: Use with care].
events        Manage bucket notification.
watch         Watch for events on object storage and filesystem.
policy	      Set public policy on bucket or prefix.
session       Manage saved sessions of cp and mirror operations.
config        Manage configuration file.
update        Check for a new software update.
version       Print version.

Docker Container

Stable

docker pull minio/mc
docker run minio/mc ls play

Edge

docker pull minio/mc:edge
docker run minio/mc:edge ls play

Note: Above examples run mc against Minio play environment by default. To run mc against other S3 compatible servers, start the container this way:

docker run -it --entrypoint=/bin/sh minio/mc

then use the mc config command.

macOS

Homebrew

Install mc packages using Homebrew

brew install minio/stable/mc
mc --help

GNU/Linux

Binary Download

chmod +x mc
./mc --help

Microsoft Windows

Binary Download

Install from Source

Source installation is intended only for developers and advanced users. mc update command does not support update notifications for source based installations. Please download official releases from https://minio.io/downloads/#minio-client.

If you do not have a working Golang environment, please follow How to install Golang.

go get -u github.com/minio/mc

Add a Cloud Storage Service

If you are planning to use mc only on POSIX compatible filesystems, you may skip this step and proceed to everyday use.

To add one or more Amazon S3 compatible hosts, please follow the instructions below. mc stores all its configuration information in ~/.mc/config.json file.

mc config host add <ALIAS> <YOUR-S3-ENDPOINT> <YOUR-ACCESS-KEY> <YOUR-SECRET-KEY> <API-SIGNATURE>

Alias is simply a short name to you cloud storage service. S3 end-point, access and secret keys are supplied by your cloud storage provider. API signature is an optional argument. By default, it is set to "S3v4".

Example - Minio Cloud Storage

Minio server displays URL, access and secret keys.

mc config host add minio http://192.168.1.51 BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12 S3v4

Example - Amazon S3 Cloud Storage

Get your AccessKeyID and SecretAccessKey by following AWS Credentials Guide.

mc config host add s3 https://s3.amazonaws.com BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12 S3v4

Example - Google Cloud Storage

Get your AccessKeyID and SecretAccessKey by following Google Credentials Guide

mc config host add gcs  https://storage.googleapis.com BKIKJAA5BMMU2RHO6IBB V8f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12 S3v2

NOTE: Google Cloud Storage only supports Legacy Signature Version 2, so you have to pick - S3v2

Test Your Setup

mc is pre-configured with https://play.minio.io:9000, aliased as "play". It is a hosted Minio server for testing and development purpose. To test Amazon S3, simply replace "play" with "s3" or the alias you used at the time of setup.

Example:

List all buckets from https://play.minio.io:9000

mc ls play
[2016-03-22 19:47:48 PDT]     0B my-bucketname/
[2016-03-22 22:01:07 PDT]     0B mytestbucket/
[2016-03-22 20:04:39 PDT]     0B mybucketname/
[2016-01-28 17:23:11 PST]     0B newbucket/
[2016-03-20 09:08:36 PDT]     0B s3git-test/

Everyday Use

Shell aliases

You may add shell aliases to override your common Unix tools.

alias ls='mc ls'
alias cp='mc cp'
alias cat='mc cat'
alias mkdir='mc mb'
alias pipe='mc pipe'

Shell autocompletion

You may also download autocomplete/bash_autocomplete into /etc/bash_completion.d/ and rename it to mc. Don't forget to source the file to make it active on your current shell.

sudo wget https://raw.githubusercontent.com/minio/mc/master/autocomplete/bash_autocomplete -O /etc/bash_completion.d/mc
source /etc/bash_completion.d/mc

mc <TAB>
admin    config   diff     ls       mirror   policy   session  update   watch
cat      cp       events   mb       pipe     rm       share    version
