print fields using awk

[Sandman!]

Try the awk script below. It basically extends JRF's script if there is more than one VG present:

# awk '/VOLUME GROUP/{if(a) printf("%s ",a);a=$3}
/PP SIZE/{if(b) printf("%s ",b);b=$6}
/TOTAL PPs/{if(c) printf("%s ",c);c=$6}
/FREE PPs/{if(d) printf("%s\n",d);d=$6}
END{print a,b,c,d}' inp

Hmm, I get output if you assume that you made two copies of your initial lsvg output. Sandman does have the free after the total.

Here my suggested changes that prints complete lines:
awk '
BEGIN { VG=""; SZ=""; FREE=""; TOT="" }
/VOLUME GROUP/ {
   if (VG) print VG "," SZ "," FREE "," TOT
   VG=$3
}
/PP SIZE/ {SZ=$6}
/TOTAL PPs/ {TOT=$6}
/FREE PPs/ {FREE=$6}
END { print VG "," SZ "," FREE "," TOT }'

The BEGIN isn't strictly needed.
You could use OFS like JRF did in his print.
