B=seq -s " " -f"iconback%02g" 1 $A
C=seq -s " " -f"img%0g" 1 $A
请问哪位知道如何让B，C 打印出来的值一一对应，例如：img1="iconback01",img2="iconback02"....
seq没法支持两个变量，用awk来
awk 'BEGIN { for(i=1; i< 10; i++) printf "img%d=iconback%02d\n", i,i}'
img1=iconback01
img2=iconback02
img3=iconback03
img4=iconback04
img5=iconback05
img6=iconback06
img7=iconback07
img8=iconback08
img9=iconback09
