Pro tip: Test on a clean VPS

Common variations & advanced usage Every experienced Linux user has been there: you install something, or move directories around, and suddenly command not found appears for tools you know are installed. You check which, type, echo $PATH, and still waste 10-20 minutes hunting down the issue. I've done it more times than I care to admit — especially after fresh server setups or when cleaning up dotfiles. That's why I built (and now constantly use) a Bash $PATH Debugger. Here's how it works in practice: Try it here: Bash $PATH Debugger The debugger takes your raw $PATH string and analyzes every directory with these checks: It even highlights common problems like missing ~/.local/bin, collapsed entries after moves, or directories that exist but aren't in your current session. "command not found" (exit code 127) is one of the most searched Bash errors online. Yet most resources just tell you to export PATH=... manually without diagnosing why it broke. This tool does the diagnosis for you. It's especially powerful on fresh VPS setups, after migrating user accounts, or when working with Docker/container environments where PATH behaves differently. One of my favorite workflows is spinning up a fresh $4-5/mo VPS, installing my usual tools, running them through the debugger, and copying the optimized PATH into my base server image. The tool also supports: Full interactive tool with live diagnosis, cleaned PATH generator, and detailed explanations:
