Here how it works

Code:

$ cat filename | awk -F '-' '{$NF=""; $(NF-1)=""; print }' | sed 's/ /-/g' | sed 's/--$//g' | sed 's/>-/> /g' 

fq-bar-something-1.0-r1.src.rpm------> fq
fq-bar-xx-r1-rel.src.rpm------------> fq
fq-bar-ff-ver-11-rel.src.rpm----------> fq-bar

That doesn't get what I want. please see my expected ouput
