LOOPS

Loops in bash allows us to repeat a series of evaluations across a number of values. The values are typically in a sorted numerical range (1-10), but they can also be a list of values. Arrays are often used to store the ranges or lists.

Types of loops

While there are several types of bash loops, among the most used are:

• IF/THEN/ELSE
  • Conditional comparison
• WHILE
  • repeat commands until a condition is met
• FOR
  • repeat commands for a list OR
  • repeat commands over a range.
