Platforms count differently and update at different times.

What this skill does

It reads a file list from standard input and invokes the specified command. Examples include rebuilding source files, running tests, or reloading a persistent process. Because it can execute arbitrary commands, review the watched paths and command effects first.

What you can do with it

  • Watch source files and rebuild a project when they change.
  • Run tests after relevant files are updated.
  • Reload a persistent child process during development.

When to use it

  • When a local command-line task should run in response to file changes.
  • Before execution, when reviewing the watched file scope and command side effects.

Example prompts

Generated from the skill’s documentation as examples; not results of actual runs.

Propose an entr setup to run tests when files in this directory change, and explain which paths will not be watched.
Review what this watch command could execute without running it.

The counting method changed in 2026-09: skills with the same name are now counted separately by author, and the full catalog is covered. Dashed lines show months before the change; they are not compared with later months, and no growth is computed across the change.

# entr (Event Notify Test Runner)

A utility for running arbitrary commands when files change.

## Usage
Show all (45 lines)

`entr` takes a list of filenames from standard input and executes the utility specified as the first argument.

### Syntax
```bash
<file_listing_command> | entr <utility> [arguments]
```

### Options
- `-c`: Clear the screen before invoking the utility.
- `-r`: Reload a persistent child process (e.g., a server).
- `-s`: Evaluate the first argument using the interpreter specified by `SHELL`.

## Examples

**Rebuild project when sources change:**
```bash
find src/ -name "*.c" | entr make
```

**Run tests when JS files change:**
```bash
git ls-files | grep '\.js$' | entr npm test
```

**Auto-reload a Node server:**
```bash
ls *.js | entr -r node app.js
```

## Agent Notes
`entr` blocks the terminal. When using it as an agent:
1. Use `process` tool to run it in the background if you need to do other things.
2. Or use it for a quick "watch mode" session where you intend to monitor output for a while.
