Looping is a fundamental concept that allows code to be executed repeatedly based on a condition. Common loop structures include for, while, and do-while. They are used to iterate through collections, perform repetitive tasks, or execute code until a certain condition is met. Cricbet99.Green

for i in {1..99} do if [[ i; fi done

Practice with while loop

i=1
while [ $i -lt 100 ]
do
    if [ `expr $i % 2` -ne 0 ];
    then
        echo $i
    fi;
i=`expr $i + 1`
done

for i in {1..99} do if ((i fi done
