Question

Do you guys know how to run terminal commands from you GUI application? I need the coding for my app. For example, if I type “netstat” in terminal it will give me all the ports. I want to this from my xcode app. Is that possible? BTW it’s not just the “netstat” command it could be “sudo…. “

Thanks,
Kevin

Here is some code I just cut out of one on my apps that uses NSTask.

NSTask* task = [[[NSTask alloc] init] autorelease];
[task setLaunchPath: @"/usr/bin/java"];

NSArray* args = [NSArray arrayWithObjects: @"-jar", jar, @"--cue", inp, @"--dir", dir, mp3, nil];
[task setArguments: args];

taskOutputFile = [[self createTmpFile] retain];
NSFileHandle* taskOutput = [NSFileHandle fileHandleForWritingAtPath:taskOutputFile];

[task setStandardOutput: taskOutput];
[task launch];

This launches an app (java) and records the output in a temp file
