Rob Pike and Brian Kernighan wrote a paper together ("cat -v considered harmful", Usenix conference 1983 if memory serves correctly) which later was the basis for the book "Programming in the UNIX environment" by the same authors. It should be a set book for every beginner in the UNIX world.

Here is a standard-conforming way of numbering lines, using sed. Interestingly enough i noticed that all three invocations of sed are necessary, it won't work with two:

Code:
echo 'a,b,c,d' | sed ':start;/,/ {h;s/,.*//p;g;s/^[^,]*,//;b start;}' | sed = | sed 'N;s/\n/   /'

I hope this helps.
