javascript - Check what files are present in remote directory with grunt -

i'm looking way check files present in remote directory want access via ssh or similar , write filenames array.

so far had no luck. unix rsync has -n flag can print every file present @ destinated location, don't how use rsync-output in grunt.

here's how might via sftp ssh2:

var ssh2 = require('ssh2');  var conn = new ssh2(); conn.on('ready', function() {   conn.sftp(function(err, sftp) {     if (err) throw err;     sftp.readdir('/tmp', function(err, list) {       if (err) throw err;       console.dir(list);       conn.end();     });   }); }).connect({   host: '192.168.100.100',   port: 22,   username: 'frylock',   // password: 'foobarbaz',   privatekey: require('fs').readfilesync('/here/is/my/key') });
