linux dialog 源码,Linux dialog详解(图形化shell)
4.密碼框
格式：
dialog? --passwordbox text height width [init]
例子：
1
2
# dialog --title "Password"? --passwordbox \
"Please give a password for the new user:"
10
35
這樣我們的密碼就暴露出來了，是不是很不安全，所以通常我們會加上一個安全選項
--insecure?? 將每個字符用*來顯示出來

# dialog? --title? "Password"? --insecure? \
