#! /bin/bash
if [ $1 = $2 ]; then
echo "$1 == $2"
elif [ $1 > $2 ]; then
echo "$1 > $2"
elif [ $1 < $2 ]; then
echo "$1 < $2"
elif [ $1 != $2 ]; then
echo "$1 != $2"
fi
参数输入 a b 结果为 a > b
输入b a 结果却是b > a ？？

得加上转义字符\
if [ $1 = $2 ]; then
echo "$1 == $2"
elif [ $1 \> $2 ]; then
echo "$1 > $2"
elif [ $1 \< $2 ]; then
echo "$1 < $2"
elif [ $1 != $2 ]; then
echo "$1 != $2"
