Linux how to recursively change permissions
To recursively modify file and directory permissions in Linux, use the chmod-R command. 1. Use digital permissions: chmod-R755/path/to/directory set all files and directories to 755, but it is better to use the find command to set directory and file permissions respectively, such as find/path/to/directory-typed-execchmod755{}\; set directory to 755, find/path/to/directory-typef-execchmod644{}\; set file to 644. 2. Use symbol permissions: chmod-Ru rwx can be used to grant read, write and execute permissions to the owner.
