Search and Remove Lines within File

Hello,

I've searched through the scripting section but could not find what I need.

I need to search for empty sections within a file and remove them.

Here is an example file:
Code:
 
Title 123
A
B
C
D
E
 
Title 098
 
Title 567
Z
Y
X

I need to remove “Title 098” because it is empty, but keep sections and title header for “Title 123” & “Title 567”

So the output would be:

Code:
 
Title 123
A
B
C
D
E
 
Title 567
Z
Y
X

The "Title" is the common header of all sections from all inputed files. I use /bin/sh.

Any assistance would be GREATLY appreciative

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
