 MINIX is a great tool for learning about Linux. MINIX is like a small and simplified version of Linux - Linus took heavy inspiration from it, and his legendary ["nothing big"](https://www.cs.cmu.edu/~awb/linux.history.html) post announcing Linux was first posted on the comp.os.minix news board. Within MINIX you will find many familiar Unix/Linux tools and features, including:
 
 - A similar directory structure: files such as /etc/utmp, /etc/passwd, /dev are where you expect them to be.
-- A Bash interpreter (ash) with source code.
+- A POSIX sh interpreter (ash) with source code.
 - Similar filesystem conventions: just as in Linux, you can mount filesystems directly onto the root filesystem with `mount`.
 - A similar system administration structure, with familiar utilities like `chmod`, `mkfs`, `mkisofs` (`genisoimage`), `part` (similar to `fdisk` or `parted`) an Emacs clone (elle), and a Vim clone (evil).
