VI Search and Replace problem help...
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
Give the vi command for replacing all occurances of the string "DOS" with the string "UNIX" in the whole document that is currently being edited. what are the commnads for replacing all occurances of the strings "DOS" and "WINDOWS" with the string "UNIX" from all lines that start or end with these strings in the document being edited?


2. Relevant commands, code, scripts, algorithms:



3. The attempts at a solution (include all code and scripts):
Part 1 was easy,
Code:
:%s/DOS/UNIX/g

But part two is what I am having trouble with. I can replace all instances at the end of the line, but not the instances IN the line that end with that word. My best solutions are
Code:
:%s/^\(DOS\|WINDOWS\)/UNIX/g
:%s/\(DOS\|WINDOWS\)$/UNIX/g

But they only replace the test "DOS" or "WINDOWS" at the beginning or end of the line with "UNIX"

So "DOS and WINDOWS are better than OS/2" Would become,
"UNIX and WINDOWS are better than OS/2" when it should be,
"UNIX and UNIX are better than OS/2"

I've tried google and the text book doesn't help at all with this. I know I have to be close but I just can't figure it out.

Thanks

drop_text_search_template

DROP TEXT SEARCH 
TEMPLATE(7)					   SQL Commands 				      DROP TEXT SEARCH TEMPLATE(7)

NAME

       DROP TEXT SEARCH TEMPLATE - remove a text search template

SYNOPSIS

       DROP TEXT SEARCH TEMPLATE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the text search template does not exist.  A notice is issued in this case.

       name   The name (optionally schema-qualified) of an existing text search template.

       CASCADE
	      Automatically drop objects that depend on the text search template.

       RESTRICT
	      Refuse to drop the text search template if any objects depend on it.  This is the default.

EXAMPLES

       Remove the text search template thesaurus:

       DROP TEXT SEARCH TEMPLATE thesaurus;

       This command will not succeed if there are any existing text search dictionaries that use the template. Add CASCADE to drop such dictionar-
       ies along with the template.

COMPATIBILITY

       There is no DROP TEXT SEARCH TEMPLATE statement in the SQL standard.
