I did some more research and have a fix to microsofts Process class. But as my last answer was deleted without a reason, I have had to create a new one. So take this example… Create a windows app and stick a rich textbox on the main form, then add this to the form load… … Read more
You need to pass also \n symbol to get your command work: var spawn = require(‘child_process’).spawn, child = spawn(‘phantomjs’); child.stdin.setEncoding(‘utf-8’); child.stdout.pipe(process.stdout); child.stdin.write(“console.log(‘Hello from PhantomJS’)\n”); child.stdin.end(); /// this call seems necessary, at least with plain node.js executable
$command = ‘yourcommand’ . ‘ > /dev/null 2>&1 & echo $!; ‘; $pid = exec($command, $output); var_dump($pid);
Look at the subprocess module: a simple example follows… from subprocess import Popen, PIPE process = Popen([“ls”, “-la”, “.”], stdout=PIPE) (output, err) = process.communicate() exit_code = process.wait()
There is a parent child relation between your processes and you have to break that. For Windows you can try: Runtime.getRuntime().exec(“cmd /c start editor.exe”); For Linux the process seem to run detached anyway, no nohup necessary. I tried it with gvim, midori and acroread. import java.io.IOException; public class Exec { public static void main(String[] args) … Read more
As others have pointed out, popen() is the most standard way. And since no answer provided an example using this method, here it goes: #include <stdio.h> #define BUFSIZE 128 int parse_output(void) { char *cmd = “ls -l”; char buf[BUFSIZE]; FILE *fp; if ((fp = popen(cmd, “r”)) == NULL) { printf(“Error opening pipe!\n”); return -1; } … Read more
