chmod 777 -R on existing path getting chmod: -R: No such file or directory
提问by RandomEli
I wanted to grant operation access using sudo chmod 777 -R <path>on mac, I double checked the given path, and it's existing and no typos, but I still got chmod: -R: No such file or directory. Any ideas about why I'm getting this error?
我想sudo chmod 777 -R <path>在 mac 上授予操作访问权限，我仔细检查了给定的路径，它存在且没有拼写错误，但我仍然得到chmod: -R: No such file or directory. 关于为什么我收到此错误的任何想法？

If you look at the synopsis from the man page for chmodyou will se the following:
如果您查看手册页中的概要，chmod您将看到以下内容：
SYNOPSIS
chmod [OPTION]... MODE[,MODE]... FILE...
chmod [OPTION]... OCTAL-MODE FILE...
chmod [OPTION]... --reference=RFILE FILE...
概要
chmod [OPTION]... MODE[,MODE]... FILE...
chmod [OPTION]... OCTAL-MODE FILE...
chmod [OPTION]... --reference=RFILE FILE...
The -Rflag should be used before the actual file mode, so you need to call the command like this:
该-R标志应在实际文件模式之前使用，因此您需要像这样调用命令：
sudo chmod -R 777 <path>
Right now you are trying to set 777permission on a file named -Rwhich of course does not exist.
现在您正在尝试为777一个名为的文件设置权限，该文件-R当然不存在。
