Use the -entry option to create a text entry dialog. Zenity returns the contents of the text entry to standard output.
The text entry dialog supports the following options:
Specifies the text that is displayed in the text entry dialog.
Specifies the text that is displayed in the entry field of the text entry dialog.
Hides the text in the entry field of the text entry dialog.
The following example script shows how to create a text entry dialog:
#!/bin/sh
if zenity --entry \
--title="Add an Entry" \
--text="Enter your _password:" \
--entry-text "password" \
--hide-text
then echo $?
else echo "No password entered"
