要求:找出100以内所有能被3整除的数,每行显示8个数,然后换行显示.
实现脚本:
#!/bin/bash#chapter_8-6m=1for ((i=1;i<=100;i++))do let temp=i%3 if [ $temp -ne 0 ] then continue fi echo -n "$i " let temp2=m%8 if [ $temp2 -eq 0 ] then echo "" fi let "m++"done
执行脚本:
[root@localhost scripts]# sh 8-63 6 9 12 15 18 21 2427 30 33 36 39 42 45 4851 54 57 60 63 66 69 7275 78 81 84 87 90 93 9699 [root@localhost scripts]#
