It's allways strange for me to see sed and awk in the same command line if you can avoid it
1seq 1 3 20 | awk '{ T[NR]=$1} END {for (i=1;i<=(NR-1);i++) print T[i+1],"-",T[i],"=" , T[i+1]-T[i]}' -
when you can do it , avoid pipe Show Sample Output
-3awk '{ printf "%.2f", $2/1024/1024 ; exit}' /proc/meminfo
