multiplication using awk

[satpati]

Dear all,

I am a beginner of awk.

my input file is :

1
2
3

I want to multiply each element of the columns
so that my output will be

1*2*3 = 6

How can i do this using awk.

thanks

regards

Hi

I guess it would be useless to ask you what have you tried so far.

awk 'BEGIN{m=1}{m*=$0;printf"%s%s",(NR>1?"*":""),$0}END{print"="m}' /input/file

Tested with [tt]gawk[/tt] and [tt]mawk[/tt].
