[Shabu Khan_1]

Hi,
I've an input file with the following details:

SERVER1
AAAA:11111:BLAH BLAH:BLAH
bbbb:11111:BLAH BLAH:BLAH
#--------------------------#
SERVER2
STUFF:STUFF2:11111:TEST
#--------------------------#
....

and so on ...

I want to append or prepend the lines without colon (those are the lines with server1, server2 values) to the lines that follow those values (the lines with colon)
so that my output will look something like this ....

SERVER1:AAAA:11111:BLAH BLAH:BLAH
SERVER1:bbbb:11111:BLAH BLAH:BLAH
#--------------------------------#
SERVER2:STUFF:STUFF2:11111:TEST
#--------------------------------#


How do I go about doing this ?

Any help would be greatly appreciated.

Thanks,
Shabu

There'll undoutably be good perl solutions soon, but here's a quick 'awk' solution:

awk -F':' '/^#/ { print } { if (NF == 1) { HEADER=$1; next;} ; printf( "%s:%s\n", HEADER, $0 ); }' < InputFile

Thanks Stuart !

That was pretty neat ...

a perl version...

$file="open(file);
while() {
chomp;
~ m/:/g;
if (pos) { print "$header:$_\n"; }
else { $header=$_; }
}
close(file);
