let之前打印出来的LA OA LB OB是什么?

pansue

是4个数字，因为前面有0，所以要把0去掉

let之前打印出来的LA OA LB OB是什么?

chengchow

你这是shell还是awk？
shell变量调用需要添加$
let T_A=$LA+$OA
let T_B=$LB+$TB

我这里测试没有问题
[root]# a=1
[root]# b=2
[root]# let c=a+b
[root]# echo $c
3

不需要$好吧！
   

chengchow

@yestreenstars@Shell_HAT终于学会@了
记错了
let调用确实可以不用$
你66/67行确定是贴出来的最后两句吗？
如果是let "t_a=LA+OA"
let "t_b=LB+OB"
试试
...

脚本不全，也没有范例文件，不好判断！
