I want to run a shell script on my node.js server, but nothing happened...
childProcess.exec('~/./play.sh /media/external/' + req.params.movie, function() {}); //not working Another childProcess works perfect, but the process above won't.
childProcess.exec('ls /media/external/', movieCallback); //works If I run the script in terminal, then it works. Any ideas? (chmod +x is set)
The exec function callback has error, stdout and stderr arguments passed to it. See if they can help you diagnose the problem by spitting them out to the console:
exec('~/./play.sh /media/external/' + req.params.movie, function (error, stdout, stderr) { console.log('stdout: ' + stdout); console.log('stderr: ' + stderr); if (error !== null) { console.log('exec error: ' + error); } }); 
exec('~/./play.sh /media/external/' + req.params.movie ... a safe construct?exec('sh ~/play.sh /media/external/' + req.params.movie ,function(err,stdout,stderr){ console.log(err,stdout,stderr); }) Runs your play.sh shellscript with /media/external/+req.params.movie as argument. The output is available through stdout,stderr variables in the callback.
OR TRY THIS
var myscript = exec('sh ~/play.sh /media/external/' + req.params.movie); myscript.stdout.on('data',function(data){ console.log(data); // process output will be displayed here }); myscript.stderr.on('data',function(data){ console.log(data); // process error output will be displayed here });` 
'error's or does it output any'data'tostdoutorstderr?
