How to make all files under a directory world readable on linux?
提问by Rorchackh
I want to make all files (and directories) under a certain directory world readable without having to chmod each file on its own. it would be great if there is an option to also do this recursively (look under folders and chmod 666 all files under it)
我想让某个目录下的所有文件（和目录）都可读，而不必单独对每个文件进行 chmod。如果有一个选项也可以递归地执行此操作，那就太好了（查看文件夹和 chmod 666 下的所有文件）

man 3 chmodcontains the information you are looking for.
man 3 chmod包含您要查找的信息。
chmod -R +r directory
the -Roption tells chmodto operate recursively.
该-R选项告诉chmod递归操作。

As a directory could contain links and/or bind mounts, the use of findcould ensure a finest granularity in what to do and what to not do....
由于目录可以包含链接和/或绑定挂载，因此使用find可以确保在做什么和不做什么方面有最精细的粒度....
find directory \( -type f -o -type d \) -print0 |
xargs -0 chmod ugo+r
To exclude paths under mount points:
排除挂载点下的路径：
find directory -mount \( -type f -o -type d \) -print0 |
xargs -0 chmod ugo+r
To exclude some specific files (.htaccess for sample):
要排除某些特定文件（示例为 .htaccess）：
find directory \( -type f -o -type d \) ! -name '.htaccess' -print0 |
xargs -0 chmod ugo+r

chmod -R 0444 ./folder_name
Apply the permission to all the files under a directory recursively
