~ is a shorthand to a current user home directory. So unless it's also your project directory you are doing something wrong. Other than that, clearing a directory would be
~ 是当前用户主目录的简写。所以除非它也是你的项目目录，否则你做错了什么。除此之外，清除目录将是
rm -rf ~/bin/*
And if you also want to clear the hidden files
如果您还想清除隐藏文件
rm -rf ~/bin/* ~/bin/.[a-zA-Z]*
Make sure you are not doing
确保你没有做
rm -rf ~/bin/.*
rm -rf ~/bin/.*
especially as root as it will try to clear out your entire system.
特别是作为 root 用户，它会尝试清除整个系统。

Why? Since wildcard (*) is interpreted by shell as zero or more characters of any kindthe .*will also match .(current directory) and ..(parent directory), which will result in going all the way up and then down, trying to remove each file in your filesystem tree.
为什么？由于通配符 ( *) 被 shell 解释为零个或多个任何类型的字符，.*因此也将匹配.（当前目录）和..（父目录），这将导致一路向上然后向下，试图删除您的文件中的每个文件文件系统树。

You should say "... my bin folder", not "my /bin folder". /binis an absolute path, binis a relative path.
您应该说“...我的 bin 文件夹”，而不是“我的 /bin 文件夹”。 /bin是绝对路径，bin是相对路径。
rm -rf ~/binremoves $HOME/bin, so not what you want either.
rm -rf ~/bin删除$HOME/bin，所以也不是你想要的。
Now, it depends on where you are: if you are in your project directory when you type the command, just type rm -rf bin.
现在，这取决于您所在的位置：如果您在键入命令时在项目目录中，只需键入rm -rf bin.
