awk multiple line record retrieves only one?
I have a file with a structure like this:

Code:
Database sequence: some data
Database position: number
Query: identifier
Location: number
E-value: number

       0         .     :     .     :     .
           STRINGSTRINGSTRINGSTRING
           ||||||||||||||||||||||||||||
           STRINGSTRINGSTRINGSTRING

@

Database sequence: some data
Database position: number
Query: identifier
Location: number
E-value: number

       0     .     :     .     :     .
           STRINGSTRINGSTRINGSTRING
           ||||||||||||||||||||||||||||
           STRINGSTRINGSTRINGSTRING

@

etc.
repeated for many entries, each being unique.

I am trying to capture the first line of each entry, and the first of two matching strings (it actually doesn't matter if it's the first or second, but for precision I want the first).

I found that I can separate the records using the "@" and the fields using a newline, and then print the fields I want using sed (I would post a link but the rules won't let me, yet. Thanks, GNU awk User's Manual).

So I copied the example from there as example.awk:

Code:
BEGIN { RS = "@" ; FS = "\n" }

Code:
{

              print $1
              print $8
}

and I run: awk -f example.awk test.txt > output.txt.
In output.txt, I only get the first record. It looks like

Code:
Database sequence: some data
           STRINGSTRINGSTRINGSTRING

which is what I want, but of course I want them all.

Sorry for the dumb noob question. Thanks in advance.

ttk::labelframe

ttk::labelframe(3tk)						 Tk Themed Widget					      ttk::labelframe(3tk)

__________________________________________________________________________________________________________________________________________________

NAME

       ttk::labelframe - Container widget with optional label

SYNOPSIS

       ttk::labelframe pathName ?options?
_________________________________________________________________

DESCRIPTION

       A  ttk::labelframe  widget is a container used to group other widgets together.	It has an optional label, which may be a plain text string
       or another widget.

STANDARD OPTIONS

       -class		     -cursor		  -takefocus
       -style

       See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       Command-Line Name:-labelanchor
       Database Name:  labelAnchor
       Database Class: LabelAnchor

	      Specifies where to place the label.  Allowed values are (clockwise from the top upper left corner): nw, n, ne, en, e, es, se,  s,sw,
	      ws, w and wn.  The default value is theme-dependent.

       Command-Line Name:-text
       Database Name:  text
       Database Class: Text

	      Specifies the text of the label.

       Command-Line Name:-underline
       Database Name:  underline
       Database Class: Underline

	      If  set, specifies the integer index (0-based) of a character to underline in the text string.  The underlined character is used for
	      mnemonic activation.  Mnemonic activation for a ttk::labelframe sets the keyboard focus to the first child  of  the  ttk::labelframe
	      widget.

       Command-Line Name:-padding
       Database Name:  padding
       Database Class: Padding

	      Additional padding to include inside the border.

       Command-Line Name:-labelwidget
       Database Name:  labelWidget
       Database Class: LabelWidget

	      The  name of a widget to use for the label.  If set, overrides the -text option.	The -labelwidget must be a child of the labelframe
	      widget or one of the labelframe's ancestors, and must belong to the same top-level widget as the labelframe.

       Command-Line Name:-width
       Database Name:  width
       Database Class: Width

	      If specified, the widget's requested width in pixels.

       Command-Line Name:-height
       Database Name:  height
       Database Class: Height

	      If specified, the widget's requested height in pixels.  (See ttk::frame(3tk) for further notes on -width and -height).

WIDGET COMMAND

       Supports the standard widget commands configure, cget, identify, instate, and state; see ttk::widget(3tk).

SEE ALSO

       ttk::widget(3tk), ttk::frame(3tk), labelframe(3tk)
