Conditional Statements: `if`, `else`, `case`
Implement decision-making logic in your scripts using various conditional constructs.
Making Decisions in Scripts
In shell scripting, just like in life, you often need to make decisions. Conditional statements allow your scripts to execute different commands based on whether a certain condition is true or false.
This is crucial for creating flexible and powerful scripts that can adapt to different situations or user inputs.
The Basic `if` Statement
The simplest conditional is the if statement. It checks a condition, and if that condition is true, it executes a block of commands. If false, it skips them.
The basic syntax looks like this:
if [ condition ]; then# commands to run if truefi
Remember fi to close the if block!
