K kainjow Registered Sep 8, 2005 #3 system() isn't the recommended way if you're dealing with Cocoa. The best way is to use NSTask: Code: NSTask *task = [NSTask launchedTaskWithLaunchPath:@"/bin/ls" arguments:[NSArray arrayWithObject:@"l"]];

Viro Registered Sep 8, 2005 #4 Question about NSTask. Is it portable? On systems other than Mac OS X?
K kainjow Registered Sep 8, 2005 #5 No, NSTask is part of the Cocoa API, which exists only on Mac OS X, and systems that have the GNUstep framework installed.

cfleck tired Sep 9, 2005 #6 Ok, almost there. The "system" call is what I need for at least part of it. I think I need NSTask for some other goodness. Is NSTask the only way I can go about getting the output from said system command?
