Shell scripting is scripting that uses the Windows Script Host shell. While the above answer may be true for Windows based systems, for Unix and Unix-like systems shell scripting is the ability to create a file of commands and to have them executed automatically, including unattended operation. It is used in the cases where one wishes to automate a process with a given series of commands to be used many times. Shell scripting allows one to automate processes, thereby reducing errors and misspellings by putting the commands in a file and telling the system to execute the commands.

Perl is a scripting language. It is not, however, a shell scripting language because Perl is not a shell program. A shell program is one that usually interacts with a user and provides certain user interface abilities. Perl was not designed for that purpose.

Perl is a "kitchen sink" of ways to interact with data, databases, networks, and so forth. It is a great language for manipulating text in various ways.

You should be able to download the Unix Services for Windows, version 3.5, from Microsoft (free).

In an interactive shell session the shell program waits for the user to type in a command. When receiving a command the shell program will then attempt to locate it and process (execute) the command. You are interacting with the shell. Running a shell file requires a pre-stored series of commands stored in a file. Unless the shell program you are running is interactive then the shell executes each command in sequence, without involving the user at all.
