CBX Shell: Complete Beginner’s Guide to Features & Setup

How to Troubleshoot Common CBX Shell Errors Quickly

CBX Shell is a powerful tool for interacting with systems; errors are inevitable. This guide gives concise, step-by-step troubleshooting for the most common CBX Shell problems so you can get back to work fast.

1. Start with basic checks

  1. Confirm version: Run cbx –version to ensure you’re on a supported release.
  2. Restart session: Close and reopen the shell or start a fresh terminal.
  3. Check environment: Ensure required environment variables (e.g., PATH, CBX_HOME) are set.

2. Authentication failures

  • Symptoms: “Authentication failed”, “Invalid token”, repeated password prompts.
  • Quick fixes:
    1. Refresh credentials: Re-run your login command (e.g., cbx login) and paste a fresh token.
    2. Check clock skew: Ensure system time is synchronized (NTP).
    3. Inspect config: Open /.cbx/config (or relevant config file) for malformed entries; back up and regenerate if corrupted.
    4. Revoke and reissue tokens from the managing service if suspected compromise or expiration.

3. Network & connectivity errors

  • Symptoms: Timeouts, “connection refused”, DNS failures.
  • Quick fixes:
    1. Ping the endpoint: ping or curl -v to verify reachability.
    2. Check proxy settings: Ensure HTTP_PROXY/HTTPS_PROXY are correct or unset if not using a proxy.
    3. Inspect firewall: Confirm port access (commonly 443) and corporate firewall rules.
    4. Retry with verbose logging: cbx –verbose to capture HTTP details.

4. Command syntax / unknown command

  • Symptoms: “Unknown command”, unexpected behavior after upgrades.
  • Quick fixes:
    1. Check help: cbx –help or cbx –help for current syntax.
    2. Auto-completion: Re-enable completion or update completion scripts if tab-complete returns nothing.
    3. Confirm plugin availability: Some commands require plugins—list them with cbx plugins list.

5. Permission denied / filesystem errors

  • Symptoms: “Permission denied”, unable to write cache or logs.
  • Quick fixes:
    1. File ownership: ls -la on the file/dir (e.g., /.cbx) and chown if incorrect.
    2. Permissions: chmod u+rw on necessary files.
    3. Disk space: df -h to ensure sufficient space; clear temp files if full.

6. Corrupted local state or cache

  • Symptoms: Strange errors, stale output, or commands that previously worked failing.
  • Quick fixes:
    1. Clear cache/state: Remove or move /.cbx/cache and /.cbx/state (back them up first).
    2. Reinitialize config: cbx init or recreate config from a template.

7. Dependency or plugin conflicts

  • Symptoms: Library load errors, stack traces referencing third-party modules.
  • Quick fixes:
    1. Reinstall CBX: Use the official installer or package manager to reinstall cleanly.
    2. Check plugin versions: Update or remove incompatible plugins (cbx plugins update / cbx plugins remove).
    3. Isolate environment: Run inside a clean container or VM to confirm host-level conflicts.

8. Debugging and logging best practices

  • Enable verbose logs: cbx –debug or cbx –log-level debug.
  • Capture output: Redirect logs to a file for analysis: cbx … 2>&1 | tee cbx-debug.log.
  • Search known issues: Check the official issue tracker and changelog for recent regressions.

9. When to escalate

  • Reproducible crash with verbose logs and no obvious config/network cause.
  • Steps to include when filing a bug:
    1. CBX version and OS (cbx –version, uname -a).
    2. Exact command and flags used.
    3. Verbose/debug log file.
    4. Minimal reproducible steps.

10. Quick checklist (copy-paste)

  • cbx –version
  • cbx –help or cbx –help
  • cbx login (refresh creds)
  • ping/curl -v endpoint
  • cbx –verbose or cbx –debug → save logs
  • Move /.cbx/cache and /.cbx/state to backup and retry
  • Reinstall or update CBX and plugins

Following these steps resolves most CBX Shell issues quickly. If problems persist, gather the debug output and open a ticket with the maintainers including the items in “When to escalate.”
