Please provide shell script to Remove empty lines(space) between two lines containing strings in a file.

I was just looking at this post: https://www.unix.com/shell-programming-scripting/22893-delete-multiple-empty-lines.html.
and I am looking to achieve the same with sed. So the idea is to delete lines from a file where a certain field has no value.

Hi all,
I'm trying to remove when this condition is met: an empty and the next one
I'm using this command:
sed '/^$/N; s/&//' file
Which searches for an empty line, N attaches it to the next line, and substituing the combination with nothing.... but it is not working.
What I'm missing... (1 Reply)
Hi all !
I'm sure it is a basic question but I didn't find any threads that fit my need.

Hello:
Is there a simple way to remove empty records of FASTA format file?
A FASTA format consists of two parts: header and sequence (for non-biologist, Wiki for details of course!). The header always start with ">" for the name of the sequence. The header must be in this ONLY single line.... (9 Replies)
Hi - I have req to join broken lines and remove empty lines but should NOT be in one line. It has to be as is line by line. The challenge here is there is no end of line/start of line char.
thanks in advance

__________________________________________________________________________________________________________________________________________________NAME
code - capture the namespace context for a code fragment
SYNOPSIS
itcl::code ?-namespace name? command ?arg arg ...?
_________________________________________________________________DESCRIPTION
Creates a scoped value for the specified command and its associated arg arguments. A scoped value is a list with three elements: the
"@scope" keyword, a namespace context, and a value string. For example, the command
namespace foo {
code puts "Hello World!"
}
produces the scoped value:
@scope ::foo {puts {Hello World!}}
Note that the code command captures the current namespace context. If the -namespace flag is specified, then the current context is
ignored, and the name string is used as the namespace context.
Extensions like Tk execute ordinary code fragments in the global namespace. A scoped value captures a code fragment together with its
namespace context in a way that allows it to be executed properly later. It is needed, for example, to wrap up code fragments when a Tk
widget is used within a namespace:
namespace foo {
private proc report {mesg} {
puts "click: $mesg"
}
button .b1 -text "Push Me" -command [code report "Hello World!"]
pack .b1
}
The code fragment associated with button .b1 only makes sense in the context of namespace "foo". Furthermore, the "report" procedure is
private, and can only be accessed within that namespace. The code command wraps up the code fragment in a way that allows it to be exe-
cuted properly when the button is pressed.
Also, note that the code command preserves the integrity of arguments on the command line. This makes it a natural replacement for the
list command, which is often used to format Tcl code fragments. In other words, instead of using the list command like this:
after 1000 [list puts "Hello $name!"]
use the code command like this:
after 1000 [code puts "Hello $name!"]
This not only formats the command correctly, but also captures its namespace context.
Scoped commands can be invoked like ordinary code fragments, with or without the eval command. For example, the following statements work
properly:
set cmd {@scope ::foo .b1}
$cmd configure -background red
set opts {-bg blue -fg white}
eval $cmd configure $opts
Note that scoped commands by-pass the usual protection mechanisms; the command:
@scope ::foo {report {Hello World!}}
can be used to access the "foo::report" proc from any namespace context, even though it is private.
