[英]Executing shell commands with NSTask - Objective-C Cocoa
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 Dock
or defaults write com.apple.Finder AppleShowAllFiles YES
something like that, how would I go about doing this. 我一直在搜索几天和几个小时,我已经看到了很多这样的示例,但是无法弄清楚NSTask是如何工作的,比如说我想执行命令
killall Dock
或defaults write com.apple.Finder AppleShowAllFiles YES
这样,我将如何去做。
I know how to execute an external shell script (sh) but need to be more sophisticated and use NSTask instead. 我知道如何执行外部Shell脚本(sh),但需要更加复杂,而应使用NSTask。
Thanks for any help!! 谢谢你的帮助!!
You could do something like: 您可以执行以下操作:
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath:@"/bin/bash"];
[task setArguments:@[ @"-c", @"/usr/bin/killall Dock" ]];
[task launch];
Exactly what launch path and arguments you provide are dictated by the command you want to run and its parameters. 您提供的启动路径和参数究竟由您要运行的命令及其参数决定。
