我的bash脚本如何在命令行参数中看到循环变量？

#!/bin/bash

for i in {1..10}
do
  echo "循环变量i的值为: $i"
done

#!/bin/bash

for i in {1..10}
do
  printf "循环变量i的值为: %d\n" $i
done

#!/bin/bash

for i in {1..10}
do
  echo "$i" | awk '{print "循环变量i的值为: " $1}'
done

#!/bin/bash

for i in {1..10}
do
  echo "$i" | sed "s/^/循环变量i的值为: /"
done

#!/bin/bash

for i in {1..10}
do
  echo "循环变量i的值为: $(expr $i)"
done
