Unix Shell Scripts (2002)

 

 

In previous discussions we have talked about many of the facilities of the C shell, such as command aliasing, job control, etc. In addition, any collection of csh commands may be stored in a file, and csh can be invoked to execute the commands in that file. Such a file is known as a shell script file. The language used in that file is called shell script language. Like other programming languages it has variables and flow control statements (e.g. if-then-else, while, for, goto). In Unix there are several shells that can be used, the C shell (csh and its extension, the T C shell tcsh), the Bourne Shell (sh and its extensions the Bourne Again Shell bash and the highly programmable Korn shell ksh ) being the more commonly used.
