Hi,
thats interesting. dint know cud use irc for that.
are there any forums/ user groups where one could get
feedback on code?
sometimes while coding, we get mistakes and fix it.
But the reason for mistake is not clear and the
information is not clear in books either.
thanks,
sanjay

hi allusage of '1'
in the below script, could any one explain me the
awk 'BEGIN{OFS=FS=",";c=1}
{
n=sprintf("%03d",c++)
$3=$3n
print c
}
1' "file"
Here's the reply from #awk@xxxxxxxxxxxxxxxx
[23:31] <karolisl> floyd_n_milan: awk '1' file
[23:31] <karolisl> try this one.
[23:31] <karolisl> it would work the same as cat.
[23:32] <floyd_n_milan> so what exactly does it do?
[23:33] <karolisl> floyd_n_milan: IMO, it works as :
or true in shell
[23:33] <floyd_n_milan> hmmm
[23:34] <floyd_n_milan> same as print then?
[23:34] <karolisl> (in this case)
[23:34] <karolisl> floyd_n_milan: one can omit print
[23:34] <karolisl> awk '/foo/'
[23:34] <karolisl> awk '/foo/' file
[23:34] <karolisl> would work as a grep/.
[23:34] <floyd_n_milan> it does :
[23:34] <karolisl> because, if a pattern/an
address/a condition is specified,
awk defaults to print as an action for that block
