[Bash] 怎么让这个循环反着来

kxmp

#!/bin/bash

# nested-loop.sh: Nested "for" loops.

outer=1 # Set outer loop counter.

# Beginning of outer loop.
for ((a = 0; a<5; a++));
do
echo "Pass $outer in outer loop."
echo "---------------------"
inner=1 # Reset inner loop counter.

# ===============================================
# Beginning of inner loop.
for ((b = 0; b < 4; b++));
do
echo "Pass $inner in inner loop."
let "inner+=1" # Increment inner loop counter.
done
# End of inner loop.
# ===============================================

let "outer+=1" # Increment outer loop counter.
echo # Space between output blocks in pass of outer loop.
done
# End of outer loop.

exit 0

Pass 1 in outer loop.---------------------Pass 1 in inner loop.Pass 2 in inner loop.Pass 3 in inner loop.Pass 4 in inner loop.Pass 2 in outer loop.---------------------Pass 1 in inner loop.Pass 2 in inner loop.Pass 3 in inner loop.Pass 4 in inner loop.Pass 3 in outer loop.---------------------Pass 1 in inner loop.Pass 2 in inner loop.Pass 3 in inner loop.Pass 4 in inner loop.Pass 4 in outer loop.---------------------Pass 1 in inner loop.Pass 2 in inner loop.Pass 3 in inner loop.Pass 4 in inner loop.Pass 5 in outer loop.---------------------Pass 1 in inner loop.Pass 2 in inner loop.Pass 3 in inner loop.Pass 4 in inner loop.


我怎么让他变成
Pass 1 in inner loop.Pass 2 in inner loop.Pass 3 in inner loop.Pass 4 in inner loop.
Pass 1 in outer loop.---------------------

你把外层循环的那句话放到里层结束之后不就好了……
