AWK's printf strange behavior

[sapfeer]

Hi! Can someone explain the following:

/tmp # uname -sr
HP-UX B.11.31

/tmp # cat testf
1,1,1,1,NODE,1,1,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,2,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,3,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,4,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,5,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,6,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,7,1,1,1,1,1,1,1,1,1
1,1,1,1,NODE,1,8,1,1,1,1,1,1,1,1,1

/tmp # awk -F"," '{clients[$5]+=$7}
END { for (client in clients)
printf "%s\t-\t\t%d" client, clients[client] }' testf
awk: There are not enough parameters in printf statement %s     -               %dNODE.
 The input line number is 8. The file is testf.
 The source line number is 3.

/tmp # awk -F"," '{clients[$5]+=$7}
END { for (client in clients)
print client,"-", clients[client] }' testf
NODE - 36

I'm a bit confused...

Hi

Missing comma ( , ) :

awk -F"," '{clients[$5]+=$7}
END { for (client in clients)
printf "%s\t-\t\t%d"[COLOR=red yellow],[/color] client, clients[client] }' testf

Hi

Nothing to apologize for. [tt]awk[/tt]'s error messages are not always accurate, so they can fool you abit on Monday morning.

One thing. Personally I prefer to format the [tt]printf[/tt] output by specifying field widths :

[b]printf[/b] [green][i]"%-8s-%17d"[/i][/green][teal],[/teal] client[teal],[/teal] clients[teal][[/teal]client[teal]][/teal]

Yeah, it's a good fashion. But mostly, you don't know the right width to specify...

Actually, I'm not an awk programmer, I'm just using it sometimes. So, such cases are more rare than usual...

Thanks a lot for explaination! It's great that there is a forum for such a small bit of all IT world like awk programming! I'm quite surprised
