comment Purpose of permissions such as 0111 or 0333
Unless it's a script (eg. shell-script) you actually don't need read-permission to execute a command. A "normal" executable -- eg. su, bash or vi -- just need the executable-bit to be set, to allow a user to run it. A file that can't be read, can't be copied. So by not allowing a user to copy a security-important command (like su), he's prevented from making his own copy of it -- and also from trying disassemble it. *BSD has several commands with execute but no read permission.

comment What is the meaning of 'ln -sf' in Linux?
To add a reason to terdon's answer... One of the usage is when manually updating libraries. If you do it in two steps - first rm to remove the old link, then ln -s to create a new one - the library won't work between the operations... which becomes a great problem if the ln command needs the library to work. So with ln -sf , the old link is replaced with a new, without the link ever being broken.

comment What does “,,,” mean in the 5 column in /etc/passwd file?
@Sebb. No it's not, it's the ':' that are important. Commands that do need to parse this field (or fields), work just as happily if the field just contain your real name (with spaces and so on).
