Loops

Loops allow repeated execution of commands.

Loop Type	Syntax Example	Notes
for	for i in 1 2 3; do echo $i; done	Iterates over a list
while	while [ $count -lt 5 ]; do echo $count; count=$((count+1)); done	Executes while condition true
until	until [ $count -ge 5 ]; do echo $count; count=$((count+1)); done	Executes until condition true

Input:

count=1
while [ $count -le 3 ]; do
  echo "Count: $count"
  count=$((count+1))
done

Output:

Count: 1
Count: 2
Count: 3

Explanation: Loops increment count and stop when the condition fails.
