需要有关在终端中执行的脚本的帮助

Question

谁能告诉我这个脚本有什么问题？

`for i in {1..7};

do for j in {1..5};

 $a =$ix630;

 $y =$jx900;

 do 
mogrify 
-crop $ax$y+675+900 +repage /home/vas/Documents/Web_Design/Mold%20ISEF%202014/poster/Ready/body_final.png; 

done;

 done`

Answer 1

您是否尝试在嵌套for循环中执行一些乘法并将值分配给a和y？

检查此处生成的值：

#!/bin/bash

for i in {1..7}; do
    for j in {1..5}; do
        a=$(( $i*630 ))
        y=$(( $j*900 ))
        echo "a: " $a "y: " $y
    done
done
