One liner:
for i in {1..9}; do echo ${i}; done
Multiple Lines:
for i in {1..9}
do
echo ${i}
done
Different ranges:
for i in {1..9}; do echo ${i}; done
for i in apple banana cherry; do echo ${i}; done
for i in $(<Command>); do echo ${i}; done
ARR=('apple' 'banana' 'cherry')
for i in "${ARR[@]}"; do echo ${i}; done
Break and continue work as expected.
