Permissions Notes

Change permissions on a directory recursively without applying Execute to files

Using a large "X" applies execute to Directories but not files.

chmod -R u=rwX,g=rwX docker-compose-files/

SetGID

Having an s in the permissions list of ls -al is the setgid bit. When another user creates a file or directory under such a setgid directory, the new file or directory will have its group set as the group of the directory's owner, instead of the group of the user who creates it.

• Add s with chmod g+s directory
• Remove it with -s
