yet another awk field syntax question

Shell Programming and Scripting
1

I am trying to print the remaing fields and field numbers beginning with a field 'xyz'

#cat abc
test1:test2:xyz:test3:test4:test5

#cat def
test1:test2:test3:xyz:test4:test5

desired output is to be able to print NF and any trailing fields separated by':'

test3 3
or
test4 3
or
test5 3

likewise,

test4 2
or
test5 2

placeing a field separator as 'xyz' illiminates using ':' as a second separator or is that possible?

2 
awk -F: -v OFS="\nor\n" ' { sub(".*xyz:",""); for(i=1;i<=NF;++i) $i=$i" "NF ;print }  ' file

I'm gonna use sed for the time being, but would like to know the correct awk syntax as well

cat abc | sed 's/\(.*\)xyz://' | awk -F: '{print $1,NF}'

edit*

thanks, i'll try it

You can do everything in awk.Check my previous post

yeah works well, a little too well! i was looking for a more simplified version by printing the fields individually, but the 'sub' syntax is what i was looking for. I'll tweek it for future applications.

thanks again
