The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script which sets up the environment, runs the program, and does any necessary clean-up, logging, etc. is called a wrapper.
The term is also used more generally to mean the automated mode of running an operating system shell; in specific operating systems they are called other things such as batch files (MSDos-Win95 stream, OS/2), command procedures (VMS), and shell scripts (Windows NT stream and third-party derivatives like 4NT—article is at cmd.exe), and mainframe operating systems are associated with a number of terms.
The typical Unix/Linux/Posix-compliant installation includes the Korn Shell (ksh) in several possible versions such as ksh88, Korn Shell ’93 and others. The oldest shell still in common use is the Bourne shell (sh); Unix systems invariably also include the C Shell (csh), Bourne Again Shell (bash), a remote shell (rsh), a secure shell for SSL telnet connections (ssh), and a shell which is a main component of the Tcl/Tk installation usually called tclsh; wish is a GUI-based Tcl/Tk shell. The C and Tcl shells have syntax quite similar to that of said programming languages, and the Korn shells and Bash are developments of the Bourne shell, which is based on the ALGOL language with elements of a number of others added as well. On the other hand, the various shells plus tools like awk, sed, grep, and BASIC, Lisp, C and so forth contributed to the Perl programming language.
Other shells available on a machine or available for download and/or purchase include ash, msh, ysh, zsh (a particularly common enhanced Korn Shell), the Tenex C Shell (tcsh), a Perl-like shell (psh) and others. Related programs such as shells based on Python, Ruby, C, Java, Perl, Pascal, Rexx &c in various forms are also widely available. Another somewhat common shell is osh, whose manual page states it “is an enhanced, backward-compatible port of the standard command interpreter from Sixth Edition UNIX.”
Windows-Unix interoperability software such as the MKS Toolkit, Cygwin, UWIN, Interix and others make the above shells and Unix programming available on Windows systems, providing functionality all the way down to signals and other inter-process communication, system calls and APIs. The Hamilton C Shell is a Windows shell that is very similar to the Unix C Shell. Microsoft distributes Windows Services for UNIX for use with its NT-based operating systems in particular, which have a Posix environmental subsystem.
