or
Code:
nawk -F\; -v OFS=' ' '$6==52 {$1=$1; print $0}' data
or
nawk -F\; -v OFS=' ' '$6==52 && $NF=$NF' data

You gotta tell us what kind of box you have. If its a Sun, use nawk instead of awk.

I love awk and understand all of the above up to your post, vgersh99. I don't understand what assigning the first field to itself (i.e. $1=$1) or number of fields to itself ($NF=$NF) does. Please broaden my horizon. Smilie
