chmod 777 -R在获取chmod的现有路径上:-R:无此类文件或目录 [英] chmod 777 -R on existing path getting chmod: -R: No such file or directory

问题描述

我想在Mac上使用sudo chmod 777 -R <path>授予操作访问权限，我再次检查了给定的路径，它既存在又没有错别字，但是我仍然得到了chmod: -R: No such file or directory.关于我为什么会收到此错误的任何想法?

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?

推荐答案

如果您从chmod手册页上查看简介，则会发现以下问题:

If you look at the synopsis from the man page for chmod you will se the following:

简介
chmod [OPTION] ... MODE [，MODE] ... FILE ...
chmod [OPTION] ... OCTAL-MODE文件...
chmod [OPTION] ... --reference = RFILE FILE ...

SYNOPSIS
chmod [OPTION]... MODE[,MODE]... FILE...
chmod [OPTION]... OCTAL-MODE FILE...
chmod [OPTION]... --reference=RFILE FILE...

-R标志应在实际文件模式之前使用，因此您需要这样调用命令:

The -R flag should be used before the actual file mode, so you need to call the command like this:

sudo chmod -R 777 <path>

现在，您正在尝试为名为-R的文件设置777权限，该文件当然不存在.

Right now you are trying to set 777 permission on a file named -R which of course does not exist.
