Question 1

How do I use shx to delete files in my npm scripts?

Accepted Answer

Install shx as a dev dependency with `npm install shx --save-dev`, then add a script like `"clean": "shx rm -rf build/"` in your package.json. Remember to double-quote glob patterns, such as `"build/**/*.js"`, for cross-platform safety.

Question 2

What's the difference between shx and ShellJS?

Accepted Answer

Shx is a CLI tool optimized for one-liner commands in npm scripts, while ShellJS is a Node.js library for writing longer JavaScript-based shell scripts. Use shx for simple package.json tasks and ShellJS for complex, programmatic operations.

Question 3

Does shx work on Windows without installing Bash or WSL?

Accepted Answer

Yes, shx runs natively on Windows by providing Unix-like commands through Node.js, so you can use `rm` or `cp` directly. However, note the quoting differences for arguments, as Windows requires escaped double quotes in package.json.

Question 4

How to handle text replacement with sed in shx?

Accepted Answer

Use `shx sed -i "s/old/new/g" file.txt`, but escape forward slashes in the pattern with `/`. For example, in package.json, write `shx sed -i "s/original\/replacement/g" file.txt` to avoid syntax issues, as per the README notes.

Question 5

Is shx faster than using bash or PowerShell directly?

Accepted Answer

No, shx is generally slower due to Node.js process overhead, making it less ideal for performance-critical tasks. It excels in cross-platform consistency for simple commands, but native shells are faster for bulk operations.

Question 6

Can I extend shx with custom commands?

Accepted Answer

Yes, shx supports ShellJS plugins. Install a plugin via npm, and shx will automatically incorporate it, allowing you to add new commands without core modifications, as mentioned in the plugin support section.
