最近使用dialog写图形自动化shell脚本, 功能很强大,功能不是非常多但是足够用。想写一篇linux下dialog的使用方法,虽然命令不多,但是写起来也需要下很大功夫,而且不一定写得更好,在网上发现一篇linux shell图形化脚本文件,于是转过来了.
liunx 下的dialog 工具是一个可以和shell脚本配合使用的文本界面下的创建对话框的工具。
每个对话框提供的输出有两种形式:
1. 将所有输出到stderr 输出,不显示到屏幕。
2. 使用退出状态码,“OK”为0,“NO”为1,”ESC”为255
窗体类型:
[ --yesno ] 提供一个带有yes和no按钮的简单信息框 (是/否框)
如果没有此包请先安装
yum -y install dialog
命令示例:
1.消息框 格式:dialog – -msgbox text height width
