linux+整数比较不能用=

#!/bin/bash

num1=10
num2=20

# 检查num1是否等于num2
if [ "$num1" -eq "$num2" ]; then
    echo "Numbers are equal."
else
    echo "Numbers are not equal."
fi

# 检查num1是否小于num2
if [ "$num1" -lt "$num2" ]; then
    echo "num1 is less than num2."
else
    echo "num1 is not less than num2."
fi

# 其他比较运算符的使用类似

int num1 = 10;
int num2 = 20;

if (num1 == num2) {
    printf("Numbers are equal.
");
} else {
    printf("Numbers are not equal.
");
}

num1 = 10
num2 = 20

if num1 == num2:
    print("Numbers are equal.")
else:
    print("Numbers are not equal.")
