Code:
while read A B
do 
    ( something
     something else file1 ) > out_$A
done < file2

so I am trying to do something like this but what goes into say 1.out should not be the same output that goes into 2.out. Each out file should be the output of a single line from the while loop (but that output can vary in length).

Code:
for ((i=1;i<=3;i++));
do
        while read A B
        do
                awk '{if(NR == FNR) {a[$0]} else {for (x in a) {if($0 ~ x) {print $0; next}}}}' file2 file1 > $i.out
        done
done

You want something more like this then:

Code:
while read A B
do
    ((i++))
    awk '{if(NR == FNR) {a[$0]} else {for (x in a) {if($0 ~ x) {print $0; next}}}}' file2 file1 > $i.out
done

The general solution in #8 should be useable, but it would be better to use code grouping {} instead of a new subshell () for every iteration..

Code:
for/while something
do
  { 
    code segment 
  } > file$((i+=1))
done
