We can't guess what's the problem is without any details, we don't have a crystal ball...and it doesn't make any sense to explain every command if you don't know how awk works.

Have a read of an awk tutorial:

Below command just prints the file , no lines are appended ..
Quote:
awk '/^BEGIN/{f=1}f;/^END/{f=0}' infile
Quote:
BEGIN DS
Name=$BLNAME
Pmpt=Istanza BL
Length=0
Scale=0
END DS
text
BEGIN DS
Name=$BLUSER
Pmpt=Utente BL
Length=0"
Scale=0"
END DS


Regards.

I/P Example :
Quote:
BEGIN DS
Name "$BLNAME"
Pmpt "Istanza BL"
Length "0"
Param "zz"
Scale "0"
END DS
text
some unwanted text
BEGIN DS
Name "$BLUSER"
Pmpt "Utente BL"
Length "0"
Scale "0"
END DS
O/P:
Quote:
Name "$BLNAME",Pmpt "Istanza BL",Length "0",Param "zz",Scale "0"
Name "$BLUSER",Pmpt "Utente BL",Length "0",Scale "0"
Thanks.
