      COURSE DESCRIPTION

      A shell is a command-line interpreter and typical operations performed by shell scripts include file manipulation, program execution, and printing text. A shell program (sometimes called a shell script) is a text file that contains standard UNIX and shell commands. Each line in a shell program contains a single UNIX command exactly as if you had typed them in yourself.
