Go clean detailed explanation: Efficiently clean up the compilation products

go clean command is a useful tool provided by the Go language compiler, which is used to delete unnecessary files generated during the compilation process. intermediate files and target files. Use go clean to save disk space and prevent clutter caused by too many compilation artifacts.

Command syntax

##go clean [-f] [-n] [-r] [-i] [build flags] [packages]

Options

• -f: Force deletion of all specified files without prompting for confirmation.
• -n: Prints a list of files to be deleted, but does not actually delete them.
• -r: Recursively delete the compilation products of all dependent packages.
• -i: You can ignore a dependent package and its compiled products will not be deleted.
• [build flags]: Additional build flags such as -v (verbose output) or -race (concurrency safety check) .
• [packages]: List of packages that need to be cleaned. If omitted, all dependent packages will be cleaned.

How it works

The go clean command uses dependency information in Go modules to determine which files need to be deleted. It iterates through a given package and all of its dependencies, and removes all files not related to those packages, including:

Binary files (
• .exe, .out)
Target file (*.o)
• Dependency information file (*.a)
• Test file (*_test.go)
• Other intermediate files (
• .mod, .sum, *.dir)

Practical case

Suppose you are currently working on a project called

myproject 's Go project, and want to clean up all compilation artifacts:

go clean -n

This will print a list of files that will be deleted, like this:

makefile
myproject.a
myproject_test.o

To actually delete these files, You can use the

-f option:

go clean -f

If no package name is specified,

go clean will clean the compilation products of all dependent packages. This is useful for cleaning large projects or scenarios with multiple projects in the working directory. For example, to clean the compilation products of all dependent packages in the project:

go clean -r
