在bash脚本中的变量之间复制值 [英] Copy values between variables in bash script

问题描述

如何将变量中的数值复制到bash脚本中的另一个变量中.如果是C，我会这样做

How can I copy the numeric value in a variable to another variable in bash script. If this were C, I would do

int a=0;
int b;
a=b;

我正在尝试这样做:

if [ $countip -gt $totalip ]; 
then
    $countip -eq $srctip # <-- My problem is here!
    echo $srctip
fi

推荐答案

只要说

countip=$srctip

这是任务在bash中的工作方式.这会将countip设置为srctip的值.如果你想分配srctip然后写

This is how assignment works in bash. This will set countip to the value of srctip. If you want to assign srctip then just write

srctip=$countip
