使用 NSTask 执行 shell 命令 - Objective-C Cocoa

问题描述

我为此搜索了数天和数小时，我看过很多这样的例子，但无法弄清楚 NSTask 是如何工作的，假设我想执行命令 killall 码头或 defaults 写 com.apple.Finder AppleShowAllFiles YES 类似的东西，我该怎么做.

I have been searching for days and hours for this, I have seen a lot of examples of this, but cannot figure out how NSTask works, let's say I wanted to execute the command killall Dockor defaults write com.apple.Finder AppleShowAllFiles YES something like that, how would I go about doing this.

我知道如何执行外部 shell 脚本 (sh)，但需要更复杂并使用 NSTask.

I know how to execute an external shell script (sh) but need to be more sophisticated and use NSTask instead.

感谢您的帮助！！

推荐答案

你可以这样做:

NSTask *task = [[NSTask alloc] init];
[task setLaunchPath:@"/bin/bash"];
[task setArguments:@[ @"-c", @"/usr/bin/killall Dock" ]];
[task launch];

您提供的确切启动路径和参数由您要运行的命令及其参数决定.

Exactly what launch path and arguments you provide are dictated by the command you want to run and its parameters.
