How to use the command "git count-objects" (with examples)

Git is a widely used version control system that allows developers to track and manage changes to their codebase. The “git count-objects” command is used to count the number of unpacked objects in a Git repository and display their disk consumption. It provides useful information about the size of the repository and can help identify bloated repositories that may need optimization.

Use case 1: Count all objects and display the total disk usage

Code:

git count-objects

Motivation: This use case is helpful when you want to quickly find out the number of objects stored in your Git repository and the total disk space they occupy. It provides a summary of the repository’s size and can be useful for monitoring the growth of the repository over time.

Explanation: The command “git count-objects” without any additional arguments will count all objects in the repository and display their total disk consumption. It excludes packed objects, which are stored in compressed form.

Example output:

count: 123
size: 456

In the example output above, “count” refers to the number of objects, and “size” indicates the total disk usage by those objects.

Use case 2: Display a count of all objects and their total disk usage, displaying sizes in human-readable units

Code:

git count-objects --human-readable

Motivation: Using human-readable units (such as kilobytes, megabytes, etc.) can make it easier to understand the disk space occupied by the objects in the repository. This is especially useful when dealing with large repositories and trying to estimate their storage requirements.

Explanation: The “–human-readable” argument causes the command to display object sizes in a human-readable format.

Example output:

count: 123
size: 456 KiB

In the example output above, “size” is displayed in kilobytes (KiB) instead of bytes.

Use case 3: Display more verbose information

Code:

git count-objects --verbose

Motivation: When you need more detailed information about the objects in the repository, including the sizes of individual objects and their type (e.g. blobs, trees), using the “–verbose” argument can provide the necessary insights.

Explanation: The “–verbose” argument enhances the output of the command by displaying additional information about each object, including its size and type.

Example output:

count: 123
size: 456
in-pack: 789
packs: 1
size-pack: 123
prune-packable: 456
garbage: 789

The example output above includes additional details related to object packing, pruning, and garbage collection. Each metric provides valuable information for optimizing and managing the repository.

Use case 4: Display more verbose information, displaying sizes in human-readable units

Code:

git count-objects --human-readable --verbose

Motivation: Combining the “–human-readable” and “–verbose” arguments allows for a comprehensive and readable output that provides detailed information about object sizes and types in a more user-friendly format.

Explanation: This use case combines both the “–human-readable” and “–verbose” arguments to display object sizes in human-readable units, along with additional verbose information.

Example output:

count: 123
size: 456 KiB
in-pack: 789
packs: 1
size-pack: 123 KiB
prune-packable: 456 KiB
garbage: 789 KiB

In the example output above, object sizes are displayed in kilobytes (KiB), and the verbose information provides insights into object packing, pruning, and garbage collection.

Conclusion:

The “git count-objects” command is a useful tool for analyzing the size and composition of a Git repository. It provides valuable information about the number of objects and their disk consumption, helping developers optimize their repositories and manage storage requirements more effectively. By using the various arguments available, such as “–human-readable” and “–verbose,” users can tailor the output to their specific needs and gain deeper insights into their repositories.
