ebuild:tldr:a22bf

This command is using the ebuild command with the clean option to clean the build files of a specific ebuild file.

Explanation of the parts of the command:

• ebuild: This is a command-line utility used in Gentoo Linux for managing ebuild files. Ebuild files are scripts that define how packages should be built, installed, and configured.

• ${filename-ebuild}: The ${filename-ebuild} part is a placeholder that should be replaced with the actual name of the ebuild file. The syntax ${filename-ebuild} is used to reference the value of the variable filename-ebuild. It is presumed that this variable holds the name of the ebuild file.

• clean: This is an option passed to the ebuild command to instruct it to clean the build files. The exact actions performed by the clean option may vary depending on how the ebuild script is implemented, but generally, it removes any temporary or intermediate build files and resets the build environment to a clean state.

Putting it all together, the command is using the ebuild command with the clean option to clean the build files associated with the specified ebuild file.
