方法1:
for 变量 in 常量列表; do 一些命令; done;
如:
for file in `ls`; do echo $file; done;
for i in 1 2 3 4 5; do echo $i; done;
方法2:
for (( 变量初始化; 条件判断; 变量自变 )); do 一些命令; done;
如:
for (( i = 0; i < 10; i++)); do echo $i; done;
MAX=10
for (( i = 0; i < MAX ; i ++ ))
do
echo `expr $i \* $i`
# echo $[$i * $i]
done
