From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

useful for chown, less so for chmod: I almost never want my dirs and files with the same permissions, and I made this mistake a few times.

find dir -type f -exec chmod 644 -- {} +
find dir -type d -exec chmod 755 -- {} +

If all you need is to restore read permissions, you could use symbolic rather than octal:

chmod -R a+r $DIR

If you don't want to grant read permissions to everyone you can replace the a with whichever applies of ugo for user, group or other.

Go over it with a second chmod -R but with -X to add execute but only to directories
