Overview

The Linux Bash Shell Programming course is designed to give delegates practical experience in developing and writing Bash shell scripts. Most of the built-in shell commands are introduced together with the main program control structures. The course also gives practical experience using a range of Linux tools to manipulate text and incorporate into Linux Bash shell scripts.

The delegate will practise:

  • Writing simple scripts to enhance basic command output
  • Using the various shell quoting mechanisms appropriately
  • Manipulating shell variables and user-defined variables in scripts
  • Implementing conditional execution facilities
  • Using the shell's built-in loop constructs where appropriate
  • Writing scripts to trap user interrupts
  • User defined Functions
  • Developing menu-driven shell scripts
  • Backing up and restoring files
  • Scheduling background jobs using cron and at
  • Using file comparison utilities
  • Using the head and tail utilities
  • Using the cut and paste utilities
  • Using split and csplit
  • Identifying and translating characters
  • Sorting files
  • Using regular expressions
  • Translating characters in a file
  • Selecting text from files with the grep family of commands
  • Editing text files with sed
  • Creating programs with awk
