[markcallen]

Summary

• Extend install.sh OS detection to support both darwin and linux
• Install OS-appropriate defaults (dev-cache + git-cleaner on Linux; all three on macOS)
• Keep mac-cache-cleaner macOS-only with a clear Linux error
• Use ${OS} in release asset download naming in install.sh
• Build dev-cache and git-cleaner for Linux in GoReleaser
• Update root README install/release docs to reflect OS-specific behavior

Issues

• Closes Add Linux and Windows (WSL) installation support for dev-cache and git-cleaner #19

Validation

• sh -n install.sh
• make test

Pull request overview

Extends the repo’s installation and release tooling to support Linux for the cross-platform CLIs (dev-cache, git-cleaner) while keeping mac-cache-cleaner macOS-only.

Changes:

• Update install.sh to detect darwin vs linux, install OS-appropriate defaults, and use ${OS} in asset names.
• Add Linux targets to GoReleaser builds for dev-cache and git-cleaner, and generalize the combined archive name to include OS.
• Update README install/release docs to reflect OS-specific behavior.

The docs say the install script “installs from the latest GitHub release archives”, but install.sh downloads a single release asset per binary (not an archive) from .../releases/download/.... Please reword this to avoid confusing users who are troubleshooting downloads.

Suggested change

	- The script installs from the latest GitHub release archives.
	- The script downloads the latest GitHub release binaries for the selected apps from the `releases/download` assets.

The bullet “exits early with an error (without partial installs) …” doesn’t match current behavior: the script installs apps in a loop, so a failure downloading/installing the 2nd/3rd binary can leave earlier binaries already installed. Either update the wording (e.g., “may partially install”) or change the script to stage all downloads first and only move into place after all succeed.

Suggested change

	- The script exits early with an error (without partial installs) if required flags or tools are missing.
	- The script exits early with an error if required flags or tools are missing; when installing multiple apps, a failure part-way through may leave earlier apps installed (partial install).

install.sh now downloads per-app assets named ${APP_NAME}-${OS}-${ARCH} (e.g. dev-cache-linux-amd64), but in this GoReleaser config I only see a combined archive artifact (cache-cleaner-{{ .Version }}-{{ .Os }}-{{ .Arch }}) being defined. Unless there is another (missing) artifact configuration, the Linux installer URLs will 404. Consider either (a) adding GoReleaser artifacts that publish per-app binaries with the ${app}-${os}-${arch} naming for linux as well, or (b) updating install.sh to download the cache-cleaner-* archive and extract the requested binaries.

Suggested change
