Installation and upgrades
macOS and Linux
Run this in a terminal:
curl -fsSL https://download.lumenlan.com/lumenlan-cli/install.sh | sh
The installer detects macOS or Linux and arm64 or x64, downloads the matching current stable binary, and
verifies it against the stable SHA256SUMS before replacing any installed command. The default path is
~/.local/bin/lumenlan. If that directory is not on PATH, the installer prints the directory to add;
open a new terminal after changing your shell configuration.
To choose an installation directory or pin an exact release, download the script before passing options:
curl -fsSL https://download.lumenlan.com/lumenlan-cli/install.sh -o install-lumenlan.sh
sh install-lumenlan.sh --install-dir "$HOME/bin" --version v0.3.1
Windows
Run this in PowerShell:
irm https://download.lumenlan.com/lumenlan-cli/install.ps1 | iex
The default path is %LOCALAPPDATA%\Programs\Lumenlan\bin\lumenlan.exe. It is added to the current user’s
PATH; open a new PowerShell and run lumenlan version. To pin a version or directory, download the script
and run ./install.ps1 -Version v0.3.1 -InstallDir "$HOME\bin".
Manual downloads
Stable releases contain six binaries: arm64 and x64 for macOS, Linux, and Windows. Choose the matching file
under https://download.lumenlan.com/lumenlan-cli/latest/, then verify its SHA-256 with the SHA256SUMS
file in that directory before making it executable and placing it on PATH.
Upgrade, roll back, and remove
Run the automatic installer again to upgrade to the current stable release. Use --version vX.Y.Z or the
PowerShell -Version vX.Y.Z option to reproduce or roll back to a published release. The installer checks
the download and probes its version before replacement, so a partial file does not become the live command.
To uninstall, remove lumenlan or lumenlan.exe, then remove a manually configured directory from PATH.
The CLI does not retain long-lived sign-in credentials, but its workspace state directory may contain
redacted audit records and isolated output. Keep or remove that directory according to your evidence policy.
