How to delete blank line/s before and after a search pattern?
Hi,
Test file x.txt below. This file is generated by a program that I unfortunately do not have control on how it gets presented/generated.
What I am wanting to do is below:
Replace any line that starts with create to be create or replace.
Search for the REUSE SETTINGS TIMESTAMP string and delete all the blank lines that precedes it and any blank lines after it.
At the moment, I am deleting all blank lines using
The main reason I am wanting to retain some of the blank lines is for clarify and to make it easier reading the code.
While deleting all the blank lines work, it makes it difficult to read the generated code. Not removing the blank lines in the REUSE SETTINGS section gives error when running the SQL script.
If I can't use sed/awk to do what's required maybe I should be write some sort of cleansing script?

alter_operator_class
ALTER OPERATOR CLASS(7) PostgreSQL 9.2.7 Documentation ALTER OPERATOR CLASS(7)NAME
ALTER_OPERATOR_CLASS - change the definition of an operator class
SYNOPSIS
ALTER OPERATOR CLASS name USING index_method RENAME TO new_name
ALTER OPERATOR CLASS name USING index_method OWNER TO new_owner
ALTER OPERATOR CLASS name USING index_method SET SCHEMA new_schema
DESCRIPTION
ALTER OPERATOR CLASS changes the definition of an operator class.
You must own the operator class to use ALTER OPERATOR CLASS. To alter the owner, you must also be a direct or indirect member of the new
owning role, and that role must have CREATE privilege on the operator class's schema. (These restrictions enforce that altering the owner
doesn't do anything you couldn't do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator
class anyway.)
PARAMETERS
name
The name (optionally schema-qualified) of an existing operator class.
index_method
The name of the index method this operator class is for.
new_name
The new name of the operator class.
new_owner
The new owner of the operator class.
new_schema
The new schema for the operator class.
COMPATIBILITY
There is no ALTER OPERATOR CLASS statement in the SQL standard.
SEE ALSO
CREATE OPERATOR CLASS (CREATE_OPERATOR_CLASS(7)), DROP OPERATOR CLASS (DROP_OPERATOR_CLASS(7)), ALTER OPERATOR FAMILY
