This tutorial is very good and effective. A pity the following parts were not made available !

In example 2, the semicolon is useless. You could as well have this :

awk ‘BEGIN { ORS=”\n\n” } 1′

instead of :

awk ‘BEGIN { ORS=”\n\n” }; 1′

11. Print the sum of fields in all lines.

awk ‘{ for (i = 1; i <= NF; i++) s = s+$i }; END { print s }’ filname.ext

this command doesnt work out…….

please do try this

” awk ‘{for(i = 1; i <= NF; i++) s = s+$i } END { print s }' num.data"
