Re: Using NSTask to execute softwareupdate

Here's the basic NSTask stuff:


NSPipe *pipes = [NSPipe pipe];
NSTask* patchInstall = [[NSTask alloc] init];
                        [patchInstall setLaunchPath:@
"/usr/sbin/softwareupdate"];
[patchInstall setArguments:[NSArray arrayWithObjects:@"-i", [patch
objectForKey:@"patch_identifier"], nil]];
 [patchInstall setStandardOutput: pipes];

                        NSFileHandle *file = [pipes fileHandleForReading];
 [patchInstall launch];
 NSData *data = [file readDataToEndOfFile];
 [patchInstall waitUntilExit];


                          ......
                       [patchInstall release];


So i'm waiting for the task to complete, then I do my thing with the
results.

Thanks,
Colin
