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 character

` 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

With npm do:

`
npm install shell-quote
