Sh - the POSIX Shell

https://www.grymoire.com/Unix/Sh.html

This is my tutorial on the POSIX shell. The POSIX shell is probably the shell you are using on a UNIX compatible system. It's an improvement of the original Bourne shell. If you are interested in my original tutorial, it's now located on this page. The biggest difference is that the POSIX shell allows the use of $(.....) for command substitution. I've updated all of the examples to use this form of command substitution. See for more info on quoting characters.
