Examples

//*nix

var cmd=require('node-cmd');

//*nix supports multiline commands

cmd.runSync('touch ./example/example.created.file');

cmd.run(
    `cd ./example

ls`, function(err, data, stderr){ console.log('examples dir now contains the example file along with : ',data) } );

//Windows

var cmd=require('node-cmd');

//Windows multiline commands are not guaranteed to work try condensing to a single line.

const syncDir=cmd.runSync('cd ./example & dir');

console.log(`

    Sync Err ${syncDir.err}

    Sync stderr:  ${syncDir.stderr}

    Sync Data ${syncDir.data}

`);

cmd.run(`dir`,
    function(err, data, stderr){
        console.log('the node-cmd dir contains : ',data)
    }
);

//clone this repo!

var cmd=require('node-cmd');

const syncClone=cmd.runSync('git clone https://github.com/RIAEvangelist/node-cmd.git');

console.log(syncClone);

Getting the CMD Process ID

    var cmd=require('node-cmd');

var process=cmd.run('node');
console.log(process.pid);

Running a python shell from node

const cmd=require('node-cmd');

const processRef=cmd.run('python -i'); let data_line = '';

//listen to the python terminal output processRef.stdout.on( 'data', function(data) { data_line += data; if (data_line[data_line.length-1] == '\n') { console.log(data_line); } } );

const pythonTerminalInput=`primes = [2, 3, 5, 7] for prime in primes: print(prime)

`;

//show what we are doing console.log(>>>${pythonTerminalInput});

//send it to the open python terminal processRef.stdin.write(pythonTerminalInput);

Output :

>>>primes = [2, 3, 5, 7]
for prime in primes:
    print(prime)
