What are the commands used in Linux but not in Unix?
There is no answer to this question. Under UNIX and Linux, commands are either shell native or external programs found on the path (which usually includes /bin /sbin /usr/bin and ~/bin) Most UNIX and distros allow the admin to choose a shell program of choice and modify the contents of other directories and many admins allow individual users to change their personal shell and add additional executable files adding more commands. That being the case, theoretically any command can be valid under almost any UNIX or Linux. YMMV.

However, file extensions are typically used in Unix as a documentation aid that states that the file is a shell script. Common extensions are .sh, .csh, .ksh, .tcsh, .zsh, etc.

Why is Unix useful in shell programming?
The shell is both a command language and a programming language that provides an interface to the UNIX operating system (Bourne, 1978). The shell is the part of the operating system that the user interacts with, and is arguably the most important part of the operating system. Files can be created, renamed, moved and read from the shell. Computer hardware can be installed, used and removed through the shells. Program applications and scripting can be written, compiled, and ran through the shell.
