one way utilize paste bring together corresponding lines of list1.txt , list2.txt , utilize split split result multiple output files, 1 line per file.

split -a 1 -d -l 1 <(paste -d" " list1.txt list2.txt) out

the other way utilize arrays:

arr1=( $(<list1.txt) ) arr2=( $(<list2.txt) ) (( i=0; i<${#arr1[@]}; i++ )) echo "${arr1[$i]} ${arr2[$i]}" > "out$i" done

bash shell sed
