Some CLI questions
I use Ubuntu Linux, and I'd like to become more familiar with the CLI. I have these questions:
1) How to remove a directory that is not empty? The only option in man rmdir is -p and that does not do what I need. rm -R needs sudo for some reason.
2) What is a CLI command to make all the files in a directory 644, and all the directories 755 (recursive to subdirectories)?
3) Some directories are listed as:
1 byte
8 byte
16 byte
32 byte
40 byte
4 KB
8 KB
This size has nothing to do with what is in them, either. What makes the different directories show as different sizes?
Thanks in advance.
