using sed or grep to find exact match of text
Hi,
Can anyone help me with the text editing I need here. I have a file that contains the following lines for example: (line numbers are for illustration only)
1 Hello world fantasy.
2 Hello worldfuntastic.
3 Hello world wonderful.
I would like to get all those lines of text that contains the word "world" without anything after it. Meaning, I would like to have lines 1 and 3, line 2 should not be included because it contains "worldfuntastic", no space between.
1 Hello world fantasy.
3 Hello world wonderful
The problem is, there are some lines that use TAB to separate words like line 3. When I use grep "world " <filename>, this will get all lines of text with the word "world" and space after it but not those with TAB, i.e. the results would only be:
1 Hello world fantasy
line 3 is not included because "world" and "wonderful" are separated by TAB. Any suggestions, please?

Hi
This time I'm trying to grep for an exact match
e.g
cat.dog.horse.cow.bird.pig
horse.dog.pig
pig.cat.horse.dog
horse
dog
dog
pig.dog
pig.dog.bird
how do I grep for dog only so that a wc -l would result 2 in above case.
Thanks in advance

BVRML(3pm) User Contributed Perl Documentation BVRML(3pm)
NAME
XRacer::BVRML - Parser for a tiny subset of VRML generated by Blender
SYNOPSIS
use XRacer::BVRML;
DESCRIPTION
This is a parser for a tiny subset of VRML generated by Blender, so called Blender-VRML or BVRML. In fact, this parser is by no means
guaranteed to be able to parse everything that Blender could generate. I will add parsing capability to it as I see the need.
"XRacer::BVRML" parses a Blender VRML file, and stores it in an internal world representation, which can be inspected and manipulated.
"XRacer::BVRML" can also write out a C function containing GL commands which render this world object, and this function can then be used
inside an XRacer track or craft file.
CLASS METHODS
$world = XRacer::BVRML->parse ($filename [, $world]);
This function parses a BVRML file called $filename, and generates a $world object. If the second optional $world parameter is given,
then the BVRML file is parsed and the results are merged with the existing $world object.
If the parsing fails, then this function will print an error message and return "undef".
WORLD OBJECT METHODS
$nr_vertices = $world->nr_vertices;
Return the total number of vertices in the world.
$nr_faces = $world->nr_faces;
Return the total number of faces in the world.
@vertices = $world->vertices;
Aggregate all vertices in the world, and return it as a list.
@faces = $world->faces;
Aggregate all faces in the world, and return it as a list.
($smallest_x, $largest_x, $smallest_y, $largest_y, $smallest_z, $largest_z) = $world->bbox;
Return the bounding box (or bounding cuboid, to be more precise) of this world.
$world->write_display_function ([name => $function_name,] [filehandle => $filehandle,] [decl => $decl]);
Write out a C function containing GL calls which, when invoked, will display this world object. The C function is called $function_name
and will be written to the file specified by the $filehandle. The function will be declared as "void function_name (void)" unless the
$decl parameter is given, which gives the return declaration. The C function is suitable for directly linking into XRacer craft and
track files. However, it requires some support. In particular, you will need to include the header file GL/gl.h, and probably xracer.h
before the function.
