DESCRIPTION

yes/no box, menu box, input box, message box, text box, info box, checklist box, radiolist box gauge box, and password box.

OPTIONS

--clear

The screen will be cleared to the screen attribute on exit. This doesn't work in an xterm (and descendants) if alternate screen switching is enabled, because in that case slang writes to (and clears) an alternate screen.

--defaultno

The dialog box will open with the cursor over the No button.

--fb

Use full buttons. (By default, whiptail uses compact buttons).

--nocancel

The dialog box won't have a Cancel button.

--noitem

The menu, checklist and radiolist widgets will display tags only, not the item strings.

--separate-output

For checklist widgets, output result one line at a time, with no quoting. This facilitates parsing by another program.

--title title

Specifies a title string to be displayed at the top of the dialog box.

--backtitle backtitle

Specifies a backtitle string to be displayed on the backdrop, at the top of the screen.

--scrolltext

Force the display of a vertical scrollbar.

Box Options

--yesno text height width

A yes/no dialog box of size height rows by width columns will be displayed. The string specified by text is displayed inside the dialog box. If this string is too long to be fitted in one line, it will be automatically divided into multiple lines at appropriate places. The text string may also contain the sub-string or newline characters `n' to control line breaking explicitly. This dialog box is useful for asking questions that require the user to answer either yes or no. The dialog box has a Yes button and a No button, in which the user can switch between by pressing the TAB key.

--msgbox text height width

A message box is very similar to a yes/no box. The only difference between a message box and a yes/no box is that a message box has only a single OK button. You can use this dialog box to display any message you like. After reading the message, the user can press the ENTER key so that whiptail will exit and the calling shell script can continue its operation.

--infobox text height width

An info box is basically a message box. However, in this case, whiptail will exit immediately after displaying the message to the user. The screen is not cleared when whiptail exits, so that the message will remain on the screen until the calling shell script clears it later. This is useful when you want to inform the user that some operations are carrying on that may require some time to finish.

--inputbox text height width [init?

An input box is useful when you want to ask questions that require the user to input a string as the answer. If init is supplied it is used to initialize the input string. When inputing the string, the BACKSPACE key can be used to correct typing errors. If the input string is longer than can be fitted in the dialog box, the input field will be scrolled. On exit, the input string will be printed on stderr.

--passwordbox text height width [init?

A password box is similar to an input box, except the text the user enters is not displayed. This is useful when prompting for passwords or other sensative information. Be aware that if anything is passed in __

--textbox file height width

A text box lets you display the contents of a text file in a dialog box. It is like a simple text file viewer. The user can move through the file by using the UP/DOWN, PGUP/PGDN and HOME/END keys available on most keyboards. If the lines are too long to be displayed in the box, the LEFT/RIGHT keys can be used to scroll the text region horizontally. For more convenience, forward and backward searching functions are also provided.

--menu text height width menu-height
