Linux 脚本无法正常工作

Question

我有一个脚本，由于某种原因，它似乎跳过了一个步骤。

[2]) echo "Delete a User"
read -p "What is the user that you would wish to delete?" username
egrep "^$username" /etc/passwd > /dev/null
if [ $? -eq 0 ]; then
read -p "Do you want to delete their home directory also? 1(yes)/2(no)" home
else
echo "That user does not exist"
sleep 3
if [ $home -eq 1 ]; then
userdel -r $username
else
userdel $username
if [ $? -eq 0 ]; then
echo "$username deleted."
sleep 3
else
echo "$username was not deleted."
sleep 3
fi fi fi
;;

它可以工作到我询问用户是否希望删除他们的主目录。如果我点击"is"或“否”，它就会跳过并转到脚本菜单。

这就是正确缩进后脚本的外观。您可以看到，在收到用户关于删除主目录的输入后，所有内容都在 else 下，不会被执行

echo "Delete a User"
read -p "What is the user that you would wish to delete?" username
egrep "^$username" /etc/passwd > /dev/null
if [ $? -eq 0 ]; then
    read -p "Do you want to delete their home directory also? 1(yes)/2(no)" home
else
    echo "That user does not exist"
    sleep 3
    if [ $home -eq 1 ]; then
        userdel -r $username
    else
        userdel $username
        if [ $? -eq 0 ]; then
            echo "$username deleted."
            sleep 3
        else
            echo "$username was not deleted."
            sleep 3
        fi 
    fi 
fi

它应该看起来像这样

echo "Delete a User"
read -p "What is the user that you would wish to delete?" username
egrep "^$username" /etc/passwd > /dev/null
if [ $? -eq 0 ]; then
    read -p "Do you want to delete their home directory also? 1(yes)/2(no)" home
else
    echo "That user does not exist"
    sleep 3
fi
if [ $home -eq 1 ]; then
    userdel -r $username
else
    userdel $username
    if [ $? -eq 0 ]; then
        echo "$username deleted."
        sleep 3
    else
        echo "$username was not deleted."
        sleep 3
    fi 
fi
