Syntax
|
|
------
|
|
|
|
.. start-mc-diff-desc
|
|
|
|
The :mc:`mc diff` mc computes the differences between two filesystem directories
|
|
or MinIO buckets. :mc:`mc diff` lists only those objects which are missing or
|
|
which differ in size. :mc:`mc diff` does **not** compare the contents of
|
|
objects.

.. tab-set::
|
|
|
|
.. tab-item:: EXAMPLE
|
|
|
|
The following command computes the difference between an object on
|
|
a local filesystem and an object in the ``mydata`` bucket on the
|
|
``myminio`` MinIO deployment:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
mc diff ~/mydata/myobject.txt myminio/mydata/myobject.txt
|
|
|
|
.. tab-item:: SYNTAX
|
|
|
|
The :mc:`mc diff` command has the following syntax:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
mc [GLOBALFLAGS] diff SOURCE TARGET
|
|
|
|
.. include:: /includes/common-minio-mc.rst
|
|
:start-after: start-minio-syntax
|
|
:end-before: end-minio-syntax
|
|
|
|
Parameters
|
|
~~~~~~~~~~
|
|
|
|
.. mc-cmd:: SOURCE
|
|
|
|
*Required* The object to compare to the ``TARGET``.
|
|
|
|
For an object from MinIO,
|
|
specify the :mc:`alias <mc alias>` and the full path to that
|
|
object (e.g. bucket and path to object). For example:
|
|
|
|
.. code-block:: none
|
|
|
|
mc diff play/mybucket/object.txt ~/mydata/object.txt
|
|
|
|
|
|
For an object from a local filesystem, specify the full
|
|
path to that object. For example:
|
|
|
|
.. code-block:: none
|
|
|
|
mc diff ~/mydata/object.txt play/mybucket/object.txt
|
|
|
|
.. mc-cmd:: TARGET
|
|
|
|
*Required* The object to compare to the ``SOURCE``.
|
|
|
|
For an object from MinIO,
|
|
specify the :mc:`alias <mc alias>` and the full path to that
|
|
object (e.g. bucket and path to object). For example:
|
|
|
|
.. code-block:: none
|
|
|
|
mc diff play/mybucket/object.txt ~/mydata/object.txt
|
|
|
|
|
|
For an object from a local filesystem, specify the full
|
|
path to that object. For example:
|
|
|
|
.. code-block:: none
|
|
|
|
mc diff ~/mydata/object.txt play/mybucket/object.txt

|
:start-after: play-alias-only

Output Legend
|
|
~~~~~~~~~~~~~
|
|
|
|
:mc:`mc diff` uses the following legend when formatting the diff output:
|
|
|
|
.. code-block:: none
|
|
|
|
FIRST < SECOND - object exists only in FIRST
|
|
FIRST > SECOND - object exists only in SECOND
|
|
FIRST ! SECOND - Newer object exists in FIRST
