shell图形化界面

本文主要是介绍shell图形化界面,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

shell图形化界面

whiptail

在CentOS6系统中,我们可以使用setup指令来修改网卡的IP等信息,交互起来十分方便,在CentOS7系统中,setup命令已经没有了,但是还有nmtui命令,可以让我们修改IP和主机名。

whiptail命令的作用就是可以出现一个图形化界面,并且样式有很多

消息框

#!/bin/bash
whiptail --title "$HOSTNAME disk info" --msgbox "`df -h`" 30 60

--title		# 指定标题内容
--msgbox	# 指定信息内容
30			# 指定消息框为30
60			# 指定信息框宽度为60

$? 0

布尔值选择框

# 布尔值选择框
#!/bin/bash
whiptail --title "你确定要这么做" --yesno "请做出你的选择" 30 60
echo $?

yes :0
no : 1

# 案例
#!/bin/bash
whiptail --title "你的性别"  --yes-button "男" --no-button "女"  --yesno "请做出你的选择" 30 60
echo $?

交互式输入框

语法:
whiptail --title "标题" --inputbox "信息"  <高度> <宽度> <默认值>


#!/bin/bash
a=`whiptail --title "跳板机"  --inputbox "请输入ip地址" 10 60 10.0.0.7 3>&1 1>&2 2>&1 `
if [ $? -eq 0 ];then
        ssh $a
else
        echo 'bey bey'
fi

# 选项
--inputbox: 交互式
10	:高度
60 :宽度
10.0.0.7 :默认值

# 返回值
选择OK : 0
选择cancel : 1

命令本身带输入内容,输入内容可以保存在变量中

密码输入框

pass=`whiptail --title "pass" --passwordbox "请输入你的密码:" 10 60 3>&1 1>&2 2>&3`
if [ $? -eq 0 ];then
        if [ $pass == '1111' ];then
                echo "密码是$pass"
        else
                echo '密码错误'
        fi

else
        echo "bey bey"
fi



# 返回值
选择OK : 0
选择cancel: 1

命令本身带输入内容可以保存在变量中

菜单栏

# 菜单栏
a=$(whiptail --title "家里" --menu "根据菜单选" 30 60 3 \
"1" "lb01"  \
"2" "lb2" \
"3" "lb03" \
"4" "lb04" \
"5" "lb05" \
"6" "lb06"  3>&1 1>&2 2>&3)

--menu		# 菜单栏
30			# 高度
60			# 宽度
3			# 菜单显示多少行内容

# 返回值
OK :0
Cancel 	:1

选择的值会将序号保存在变量中

单选框

# 语法
a=$(whiptail --title "家里" --radiolist "根据菜单选" 30 60 3 \
"1" "lb01" OFF  \
"2" "lb2"  ON \
"3" "lb03" OFF \
"4" "lb04" OFF \
"5" "lb05" OFF \
"6" "lb06" OFF 3>&1 1>&2 2>&3)

# 选项
--rediolist : 单选框
OFF : 默认没有被选中
ON	:默认被选中

多选没有意义,后面的值会覆盖前面的选项

# 返回值
OK :0
Cancel 	:1

多选框

# 语法

a=$(whiptail --title "家里" --checklist "根据菜单选" 30 60 3 \
"1" "lb01" OFF  \
"2" "lb2"  ON \
"3" "lb03" OFF \
"4" "lb04" OFF \
"5" "lb05" OFF \
"6" "lb06" OFF 3>&1 1>&2 2>&3)

进度条

{
        for ((i = 0 ; i <= 100 ; i+=1));do
                sleep 10
                echo $i
        done
} | whiptail --gauge "让子弹飞一会" 6 60 10
