這個runCommand方法不需要腳本文件，只需運行一個命令行：

-?(NSString?*)runCommand:(NSString?*)commandToRun{
????NSTask?*task?=?[[NSTask?alloc]?init];
????[task?setLaunchPath:@"/bin/sh"];

????NSArray?*arguments?=?[NSArray?arrayWithObjects:
??????????????????????????@"-c"?,
??????????????????????????[NSString?stringWithFormat:@"%@",?commandToRun],
??????????????????????????nil];
????NSLog(@"run?command:%@",?commandToRun);
????[task?setArguments:arguments];

????NSPipe?*pipe?=?[NSPipe?pipe];
????[task?setStandardOutput:pipe];

????NSFileHandle?*file?=?[pipe?fileHandleForReading];

????[task?launch];

????NSData?*data?=?[file?readDataToEndOfFile];

????NSString?*output?=?[[NSString?alloc]?initWithData:data?encoding:NSUTF8StringEncoding];
????return?output;}

您可以這樣使用這個方法：

NSString?*output?=?runCommand(@"ps?-A?|?grep?mysql");
