The command git format-patch -${3} is used in the Git version control system to generate patch files from specific commits.

Here's a breakdown of the command:

• git format-patch: This is the Git command used to generate patch files for specific commits.
• - (dash): It is a prefix used to set options in Git commands.
• ${3}: This is a placeholder for a variable that should be replaced with an actual value when running the command. The value represents the number of commits for which patch files should be generated. For example, if ${3} is replaced with 3, it will generate patch files for the last three commits.

To use this command, you need to replace ${3} with a number indicating how many recent commits you want the patch files for. For instance, git format-patch -3 will generate patch files for the last three commits.

The command generates patch files in the format 0001-commit-message.patch, 0002-commit-message.patch, and so on, where commit-message represents the summary or title of each commit. These patch files can be shared and applied on other Git repositories using the git apply command.
