Objective c 终端OSX:；“字符串”；命令需要命令行开发人员工具

我需要从

objective-c

为了实现它，我从

obj-c

运行一个terminal命令并解析其输出

命令

ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6

-(NSString*)runCommand:(NSString*)commandToRun;
{
    NSString *output=@"";

    @autoreleasepool {
    NSTask *task;
    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;
    pipe = [NSPipe pipe];
    [task setStandardOutput: pipe];

    NSPipe *errorPipe = [NSPipe pipe];
    [task setStandardError:errorPipe];

    NSFileHandle *file;
    file = [pipe fileHandleForReading];

    NSFileHandle *errorFile;
    errorFile = [errorPipe fileHandleForReading];

    [task launch];

    NSData *data;
    data = [file readDataToEndOfFile];

    NSData* errorData;
    errorData = [errorFile readDataToEndOfFile];


    output = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

    NSString *errorOutput;
    errorOutput = [[NSString alloc] initWithData: errorData encoding: NSUTF8StringEncoding];

    }

    return output;
}

我正在使用下面给出的代码执行终端命令

ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6

-(NSString*)runCommand:(NSString*)commandToRun;
{
    NSString *output=@"";

    @autoreleasepool {
    NSTask *task;
    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;
    pipe = [NSPipe pipe];
    [task setStandardOutput: pipe];

    NSPipe *errorPipe = [NSPipe pipe];
    [task setStandardError:errorPipe];

    NSFileHandle *file;
    file = [pipe fileHandleForReading];

    NSFileHandle *errorFile;
    errorFile = [errorPipe fileHandleForReading];

    [task launch];

    NSData *data;
    data = [file readDataToEndOfFile];

    NSData* errorData;
    errorData = [errorFile readDataToEndOfFile];


    output = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

    NSString *errorOutput;
    errorOutput = [[NSString alloc] initWithData: errorData encoding: NSUTF8StringEncoding];

    }

    return output;
}

请建议一些类似命令的替代方法或任何解决方法

非常感谢您的关注。

您真的不能，最好的选择是使用

ioreg-lw0 | grep“EDID”| sed/[^
用字符串在本地过滤它-6
您能详细说明@daredevilh您是如何将上述命令发送到远程计算机的吗？实际上，我已经创建了一个应用程序（问题中提供的代码）。用户正在mac笔记本上运行应用程序，应用程序正在捕获他们的系统信息。然后，您应该运行
ioreg-lw0 | grep“EDID”| sed“/[^我按照你说的做了，但是当我运行
strings-6~/Desktop/report.txt
终端再次显示提示并说
xcode选择：注意：在“/Applications/xcode.app”中找不到开发人员工具，请求安装。请在对话框中选择一个选项下载命令行开发人员工具。
