Sed if statement (totally stuck) apache
I have a irritating problem with a "if"-statement or what you should call it, in sed. I would love some help here since I am very, very stuck.
I have this statement that I want to do:
if line contains a:
do this
if none of the lines contained a:
do this
The problem with this statement is that I cant find out if it's possible and if so, how to implement this statement. In any case I've found, both "do this" will be made and I will get two outputs.
I've tried things such as:
"/searchstring/b ifpart"
"1s/^/<!-- ELSE -->/"
"b end"
":ifpart"
"s/searchstring\1<!-- IF -->/"
":end"
The problem is that in any case, the "ELSE" comment will be printed and if the searchstring is found, the IF comment will be printed as well. I only want ONE of them simultaniously, not both. I would really love to hear if it's possible or not and if you have any clue how to do it as well
Thank you!

EXECUTE(7) SQL Commands EXECUTE(7)
NAME
EXECUTE - execute a prepared statement
SYNOPSIS
EXECUTE name [ ( parameter [, ...] ) ]
DESCRIPTION
EXECUTE is used to execute a previously prepared statement. Since prepared statements only exist for the duration of a session, the pre-
pared statement must have been created by a PREPARE statement executed earlier in the current session.
If the PREPARE statement that created the statement specified some parameters, a compatible set of parameters must be passed to the EXECUTE
statement, or else an error is raised. Note that (unlike functions) prepared statements are not overloaded based on the type or number of
their parameters; the name of a prepared statement must be unique within a database session.
For more information on the creation and usage of prepared statements, see PREPARE [prepare(7)].
PARAMETERS
name The name of the prepared statement to execute.
parameter
The actual value of a parameter to the prepared statement. This must be an expression yielding a value that is compatible with the
data type of this parameter, as was determined when the prepared statement was created.
OUTPUTS
The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE.
EXAMPLES
Examples are given in the Examples [prepare(7)] section of the PREPARE [prepare(7)] documentation.
COMPATIBILITY
The SQL standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXECUTE statement also uses a
somewhat different syntax.
