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!

ppi::statement::null
PPI::Statement::Null(3) User Contributed Perl Documentation PPI::Statement::Null(3) NAME
PPI::Statement::Null - A useless null statement SYNOPSIS
my $foo = 1; ; # <-- Null statement my $bar = 1; INHERITANCE
PPI::Statement::Null isa PPI::Statement isa PPI::Node isa PPI::Element DESCRIPTION
"PPI::Statement::Null" is a utility class designed to handle situations where PPI encounters a naked statement separator. Although strictly speaking, the semicolon is a statement separator and not a statement terminator, PPI considers a semicolon to be a statement terminator under most circumstances. In any case, the null statement has no purpose, and can be safely deleted with no ill effect. METHODS
"PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element. SUPPORT
See the support section in the main module. AUTHOR
