Just for the fun (and did not really test it): cat pkg.out | awk ' { p=$1; n=match(p, "-[[:digit:]]+"); print substr(p,1,n); } '| while read PKG; dogrep "$PKG[0-9]" update.out; done I will leave you as an exercise to sort the results by versions and head (or tail) to keep the highest one... ^_^ But, if your update.out file contained only the latest package (and not all different versions), that should work.
