removing carriage returns in text file

Shell Programming and Scripting
1

Hi

I have a text file that looks like this:
A
B
C

D
E
F

G
H
I

I want it to be reformatted to
A;B;C;
D;E;F;
G;H;I;

I want a shell script to do this. Any help is greatly appreciated.

Thanks

no need of script this sed oneliner will do it..

sed -ne 'H
/^$/{x
s/\n/;/g
s/;//
p
}' filename

$ 
$ cat f1
A
B
C

D
E
F

G
H
I

$ awk '{if (/^$/){print} else{printf("%s;",$0)}}' f1
A;B;C;
D;E;F;
G;H;I;
$ 
$
