Bourne Shell Program Control

  • Douglas William Topham

Abstract

Within a shell file (also known as a shell procedure or shell script), the shell acts as a programming language. Like other languages, the shell provides features like these:
  • Flow control commands (ifthenelse, while, for, and so on)

  • Interrupt handling (trap), variable setting, and parameter passing (refer to Chapter 23, “Bourne Shell Variables”)

  • Calls to other commands or shell procedures as subroutines
