Commit b67b94c

If you just want cross platform UNIX commands, checkout [`shx`](https://github.com/shelljs/shx).

It exposes `shelljs` to the command line.

A convenience script `shelljs/make` is also provided to mimic the behavior of a Unix Makefile.

In this case all shell objects are global, and command line arguments will cause the script to

execute only the corresponding function in the global `target` object. To avoid redundant calls,

target functions are executed only once per script.

Example:

require('shelljs/make');

target.all = function() {

target.bundle();

target.docs();

};

target.bundle = function() {

cd(__dirname);

mkdir('-p', 'build');

cd('src');

cat('*.js').to('../build/output.js');

};

target.docs = function() {

cd(__dirname);

mkdir('-p', 'docs');

var files = ls('src/*.js');

for(var i = 0; i < files.length; i++) {

var text = grep('//@', files[i]); // extract special comments

text = text.replace(/\/\/@/g, ''); // remove comment tags

text.toEnd('docs/my_docs.md');

}

};

To run the target `all`, call the above script without arguments: `$ node make`. To run the target `docs`: `$ node make docs`.

You can also pass arguments to your targets by using the `--` separator. For example, to pass `arg1` and `arg2` to a target `bundle`, do `$ node make bundle -- arg1 arg2`:

require('shelljs/make');

target.bundle = function(argsArray) {

// argsArray = ['arg1', 'arg2']

/* ... */

}
