The sections on quoting and globbing suggest this author, though obviously trying to be helpful, isn't really knowledgeable enough to be writing such a guide.

The sections on quoting and globbing suggest this author, though obviously trying to be helpful, isn't really knowledgeable enough to be writing such a guide. I suggest reading this instead: http://www.grymoire.com/Unix/Sh.html http://www.grymoire.com/Unix/Sh.html Granted, it's about the Bourne shell, but since Bash, Korn, and every standard UNIX shell is supposed to be compatible with it, it's well worth learning. And IMO, if you need more than what the Bourne shell provides, you should be using a proper programming language like Python instead.
