The original file is separated, and I only need some parts of it.
Each time I queried information I obtained a description of what I was querying and the result the line below it.
But now I need to organize data in this way:
First:
Node,Manufacturer,Model : I need all that
Second:
Node,Manufacturer,Model : I only need Manufacturer,Model (I will exclude Node from the remaining lines)
Third:
Node,AddressWidth : I only need AddressWidth (only one time will be enough)
Fourth:
Node,SerialNumber : I only need SerialNumber
Fifth:
Node,Name,Version : I only need Name,Version but only for line that contains CBMR
I am not sure if this is possible.

Here's one way using awk. Run like:
awk -f script.awk file
Contents of script.awk:
BEGIN {
FS=OFS=","
}
$1 == x=("Node") {
c++
f=sub(/[^,]*,/,"")
one = (one ? one : x) OFS $0
next
}
c==5 && $2 !~ /CBMR/ {
next
}
f==1 {
y=$1
gsub(/^[^,]*,|[ \t]*$/,"")
two = (two ? two : y) OFS $0
f=0
}
END {
print one ORS two
}
Results:
Node,Manufacturer,Model,Name,Version,AddressWidth,SerialNumber,Name,Version
NAKAMA,Dell Computer Corporation,PowerEdge 6650,Microsoft Windows Server 2003 R2 Enterprise Edition|C:\WINDOWS|\Device\Harddisk0\Partition1,5.2.3790,32,BZJS571,CBMR 5.0.1 Release 4,5.0.1
Alternatively, here's the one-liner:
awk 'BEGIN { FS=OFS="," } $1 == x=("Node") { c++; f=sub(/[^,]*,/,""); one = (one ? one : x) OFS $0; next } c==5 && $2 !~ /CBMR/ { next } f==1 { y=$1; gsub(/^[^,]*,|[ \t]*$/,""); two = (two ? two : y) OFS $0; f=0 } END { print one ORS two }' file
