带有 NSTask 的命令

Question

所以我试图在我的 mac 应用程序中运行一些基本的终端命令，但由于某种原因我无法做到。

这是我的代码：

NSString *commitText = [commitMessage stringValue];
NSString *a = [NSString stringWithFormat:@"cd %@", dirPath];
NSString *c = [NSString stringWithFormat:@"usr/bin/git commit -m '%@'", commitText];

NSTask *aTask = [[NSTask alloc] init];
NSMutableArray *args = [NSMutableArray array];
[args addObject:@"-c"];
[args addObject:a];
[args addObject:@"git add *"];
[args addObject:c];
[args addObject:@"git push origin HEAD"];

NSPipe *pipe;
pipe = [NSPipe pipe];
[aTask setStandardOutput: pipe];

NSFileHandle *file;
file = [pipe fileHandleForReading];


[aTask setLaunchPath:@"bin/sh"];
[aTask setArguments:args];
[aTask launch];

以下是错误：

我做错了什么？请帮忙。谢谢大家。

启动路径应为/usr/bin/git，您的阵列应为@[@"commit",@"-m",yourarg] 您需要为每个命令创建不同的任务。您的添加、推送需要是单独的任务。要查找 git 的路径，请在终端中运行命令 which git 这将是您的任务的路径。

NSTask* task = [[Task alloc] init]
//set the input output pipes
[task setLaunchPath:@"/usr/bin/git"];
NSArray* args = [NSArray arrayWithObjects:@"commit",@"-m",commitMessage];
[task setArguments:args];
//set up the notifications
[task launch];

如果你想使用 shell 脚本，我认为你需要给它更多格式，例如：

NSString* shScript = [NSString stringWithFormat:@"#!bin/sh\ngit commit -m %@\ngit add ...\ngit..."

将其设置为与上面相同的数组中的唯一参数该字符串和启动路径/bin/sh
