+# shell-quote
+
+Parse and quote shell commands.
+
+# example
+
+## quote
+
+``` js
+var quote = require('shell-quote').quote;
+var s = quote([ 'a', 'b c d', '$f', '"g"' ]);
+console.log(s);
+```
+
+output
+
+```
+a 'b c d' \$f '"g"'
+```
+
+## parse
+
+``` js
+var parse = require('shell-quote').parse;
+var xs = parse('a "b c" \\$def \'it\\\'s great\'');
+console.dir(xs);
+```
+
+output
+
+```
+[ 'a', 'b c', '\\$def', 'it\'s great' ]
+```
+
+## parse with an environment variable
+
+``` js
+var parse = require('shell-quote').parse;
+var xs = parse('beep --boop="$PWD"', { PWD: '/home/robot' });
+console.dir(xs);
+```
+
+output
+
+```
+[ 'beep', '--boop=/home/robot' ]
+```
+
+## parse with custom escape charcter
+
+``` js
+var parse = require('shell-quote').parse;
+var xs = parse('beep --boop="$PWD"', { PWD: '/home/robot' }, { escape: '^' });
+console.dir(xs);
+```
+
+output
+
+```
+[ 'beep', '--boop=/home/robot' ]
+```
+
+## parsing shell operators
+
+``` js
+var parse = require('shell-quote').parse;
+var xs = parse('beep || boop > /byte');
+console.dir(xs);
+```
+
+output:
+
+```
+[ 'beep', { op: '||' }, 'boop', { op: '>' }, '/byte' ]
+```
+
+## parsing shell comment
+
+``` js
+var parse = require('shell-quote').parse;
+var xs = parse('beep > boop # > kaboom');
+console.dir(xs);
+```
+
+output:
+
+```
+[ 'beep', { op: '>' }, 'boop', { comment: '> kaboom' } ]
+```
+
+# methods
+
+``` js
+var quote = require('shell-quote').quote;
+var parse = require('shell-quote').parse;
+```
+
+## quote(args)
+
+Return a quoted string for the array `args` suitable for using in shell
+commands.
+
+## parse(cmd, env={})
+
+Return an array of arguments from the quoted string `cmd`.
+
+Interpolate embedded bash-style `$VARNAME` and `${VARNAME}` variables with
+the `env` object which like bash will replace undefined variables with `""`.
+
+`env` is usually an object but it can also be a function to perform lookups.
+When `env(key)` returns a string, its result will be output just like `env[key]`
+would. When `env(key)` returns an object, it will be inserted into the result
+array like the operator objects.
+
+When a bash operator is encountered, the element in the array with be an object
+with an `"op"` key set to the operator string. For example:
+
+```
+'beep || boop > /byte'
+```
+
+parses as:
+
+```
+[ 'beep', { op: '||' }, 'boop', { op: '>' }, '/byte' ]
+```
+
+# install
+
