Tools for running multiple commands or npm scripts in parallel or sequentially.

Tools to watch your source files and run a build command whenever any of the files change.

Utilities to perform common command-line tasks without worrying about cross-platform compatibility.

rimraf - Delete files or directories; like rm -rf.
del-cli - Safer file and folder deletion.
mkdirp - Create a directory, creating parent directories if needed; like mkdir -p.
cpr - cp -r for Node.js.
cpy-cli - File/directory copying/renaming.
copyfiles - Copy a list of files into a directory.
sync-files - rsync-like directory syncing with watch mode.
echo-cli - Cross-platform echo with JS escape sequence support.
clear-cli - Clear the terminal.
cross-env - Set environment variables for scripts, unix-style.
cross-os - Run platform-specific npm scripts.
ntee - Utility that reads from standard input and writes to standard output and files; like Unix tee.
catw - Print a file to stdout, with optional watch mode; sorta like Unix cat.

shx - Collection of common Unix utilities implemented in Node.js; example usage: shx rm somefile.

hashmark - Take contents of a file and output as new file with a hash in the name.
gzip-size-cli - Get the gzipped size of a file or stdin.
opn-cli - Open websites, files, executables, etc. with the user's preferred application.
headr - Add header / banner info to a file.
Bower files CLI - Get main bower files on the command line.
cli-error-notifier - Send native desktop notifications when npm scripts fail.

Forrest - npm scripts desktop client.
run-npm - Run locally-installed node module executables. Useful for debugging npm scripts.
npm-quick-run - Quickly run npm scripts by prefix without typing the full name.

A quick reference of the shell operators & commands that work the same on Unix and Windows.

Use && to run commands in sequence. If a command fails, the script exits.
Use | to pipe the stdout of one command into the stdin of the next. (do-something | something else)
Use > to write the stdout of a command to a file. (do-something > file)
Use < to send the contents of a file to a command's stdin. (command < file)
Use cd <dir> to change the current working directory to <dir>. Note that cd alone prints the current working directory on windows, but changes the working directory to ~ on *nix.

You can use npm run-script or npm run; they both do the same thing, but npm run is shorter.

Run just npm run to print a list of scripts.
Running npm run script (where script is the name of your script) will run prescript, script, and postscript; in that order.
- You can't nest pre and post hooks (i.e. preprescript won't work).
You can pass arguments to your scripts by passing -- to npm run, followed by the arguments. Example: Given the script "mocha": "mocha", you can run npm run mocha -- --reporter xunit. This effectively runs mocha --reporter xunit.
Running npm test is the same as running npm run test. The same applies to npm start and npm stop.
You can run npm run <script> -s to silence the default npm output (useful for calling a script within another script).
