Learning Objectives

Flow Control

  • start the course
  • work with conditional statements in Bash scripts and use the built-in test command to evaluate expressions
  • recognize numeric, string, and test comparison operators and create compound conditional statements
  • work with for loops and wildcards

  • perform simple math operations in a Bash script and use the bc utility to do floating point math
  • create and use a Bash script to convert numbers between different bases
  • manipulate strings using the built-in Bash string manipulation operations
  • use popd, pushd, dirs, pwd, cd, and $DIRSTACK to work with directories and directory structures in a Bash script
