Delete Blank Lines From A File

Trying to delete blank lines from an Oracle SQLFILE.  I've tried sed '/^$/d' filename and going into vi then : /^$/d.  Neither works.
set list
-- new object type path is: DATABASE_EXPORT/SCHEMA/TABLE/GRANT/OWNER_GRANT/OBJECT_GRANT$
-- CONNECT OUTLN$
GRANT SELECT ON "OUTLN"."OL$" TO "SELECT_CATALOG_ROLE";$
 $
GRANT SELECT ON "OUTLN"."OL$HINTS" TO "SELECT_CATALOG_ROLE";$
 $
-- CONNECT SYSTEM$
GRANT SELECT ON "SYSTEM"."DEF$_AQCALL" TO "SYS" WITH GRANT OPTION;$
 $
GRANT SELECT ON "SYSTEM"."DEF$_ERROR" TO "SYS" WITH GRANT OPTION;$
 $
GRANT SELECT ON "SYSTEM"."DEF$_DESTINATION" TO "SYS" WITH GRANT OPTION;$
 $
GRANT SELECT ON "SYSTEM"."DEF$_CALLDEST" TO "SYS" WITH GRANT OPTION;$
 $
GRANT SELECT ON "SYSTEM"."DEF$_LOB" TO "SYS" WITH GRANT OPTION;$
 $
GRANT DELETE ON "SYSTEM"."DEF$_TEMP$LOB" TO "SYS" WITH GRANT OPTION;$

Is the line really blank or is it spaces filled?
cat filename | egrep -v '^\s+\$'

grep -v "^\s*$"  filename

can remove blank line or lines with only spaces.

arnoldCommented:
The problem is that to exclude something you have to know what is there

What is the issue that the blank lines are causing which leads you to have the need to have them removed??

try cat create_user.sql | grep -i '(alter|default|tablespace|path)'

cat create_user.sql | egrep -i '[a-z0-9\-]' > create_users.sql
 :-)  :-)  :-)

Basically i want to use it as a SQL script.  In all there are 800,000+ lines involved.
If I go into SQLPlus and call that as a script it will error out on any blank line between statements.
Thanks
