Tired of repetitive tasks in your scripts? The Bash `while` loop is your solution! It executes a block of code repeatedly as long as a specified condition remains true. Think of it as saying, "While this condition holds, keep doing this!".
Here's the basic syntax:
```bash
while [ condition ]
do
# Code to execute
done
```
The `condition` can be anything you can test in Bash, like comparing numbers, checking file existence, or evaluating the output of a command. The `do` and `done` keywords mark the beginning and end of the loop's body.
For example, to print numbers 1 to 5:
```bash
i=1
while [ $i -le 5 ]
do
echo $i
i=$((i+1))
done
```
This loop continues as long as `$i` is less than or equal to 5. Inside the loop, we print the value of `$i` and increment it by 1. Mastering `while` loops unlocks powerful automation in your Bash scripting.
