give column range in awk
hi all,

I generally give an awk command to print multiple columns like this:

PHP Code:
awk -F~ '{OFS=",";print $1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$11,$12,$13}' test.txt 
can't we give a range like :

PHP Code:
awk -F~ '{OFS=",";print $1-$13}' 
( I know this will subtract column 13 from 1) 

or awk -F~ '{OFS=",";print $1 to $13}' 
Thanks
Sumeet
