Description

ABOUT THE COURSE

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
