可能重复：
如果语句不遵循其条件
我认为这是我的 bc 或我的变量有问题，但我可能是错的。
这是我的一些代码。
#!/bin/bash
#this is a game that is two player and it is a race to get to
#100 before the other player
echo "Player 1 name?"
read p1
echo "Player 2 name?"
read p2
echo "Okay $p1 and $p2. $p1 will go first"
p1s=0
p2s=0
pt=1
while [ $pt -eq 1 ]; do
echo "roll or stay"
read choice
if [ $choice ="r" ]; then
die=$(($RANDOM%6+1))
if [ $choice ="s" ]; then
echo "Okay $p1 your score is $p1s"
echo "$p2 turn now"
sleep 1
count=0
pt=2
else
pt=1
fi
fi
if [ $die -eq 1 ]; then
p1s=$(echo "$p1s-$count" |bc)
echo "You rolled a 1. Your score is $p1s"
echo "$p2 turn now."
sleep 1
count=0
pt=2
elif [ $die -gt 1 ]; then
p1s=$(echo "$p1s+$die" |bc)
count=$(echo "$count+$die" |bc)
echo "You rolled a $die. Your score is $p1s"
pt=1
fi
if [ $p1s -gt 99 ]; then
echo "$p1 won. $p2 lost"
echo "would you like to play again?"
read again
else
if [ $again ="yes" ]; then
echo "Okay one second."
sleep 1
clear
bash num.sh
else
if [ $again = "no" ]; then
exit
else
echo "I guess no then?"
exit
fi
fi
fi
done
发生的事情是这样的
玩家 1 的名字？
1
玩家2的名字？
2
好的1和2。1会先走
滚动或停留
r
num.sh: 第 24 行: [: r: 一元运算符预期
num.sh：第 42 行：[：-eq：预期一元运算符
num.sh: 第 51 行: [: -gt: 一元运算符预期
好的一秒钟。
玩家 1 的名字？
在这里它会发现一堆错误等等。然后重新开始。
先感谢您。
