add 0 to empty line

[smithia6]

Last question of the day folks.

I have the script running nice now where it adds up lines of data, however some lines of data look like this.

3.2
1.1
0.5

0.2
0.2
0.2

0.1

Notice some of the lines have no data what I need to do is to add a 0 to the empty lines, how can I do this??

Regards

Ian

Try this :
[tt]
awk '{print (NF ? $0 : 0)}' input_file
[/tt]

Tried that and this is what I get

awk: syntax error near line 1
awk: illegal statement near line 1

Try nawk instead of awk

or
[tt]
awk '{if (NF) print $0; else print 0 }' input_file
[/tt]
