culmat / claude-update
Last active April 30, 2026 16:25
#!/usr/bin/env bash
# Self-service Claude Code updater.
#
# - Mirrors what `claude update` would do: picks the
# channel's target version, verifies SHA256 from the published manifest, and
# atomically swaps the ~/.local/bin/claude symlink.
# - Works around a corporate URL-filter that blocks the ELF binary at downloads.claude.ai.
# - Is faster than claude update
# - Runs on Linux and macOS.
