Right idea but you aren't using anything to anchor the pattern, so you would also match 'JohnABC, CDE, 14'
@arr1 = ("0000007 | John | ABC.txt | 42","0000014 | Jane | XYZ.txt | 3 +4","0000017 | Jessica | GHI.txt | 21", etc); @arr2 = ('0000007', '0000014'); my $re = join('|',@arr2); my @arr3 = grep /^(?:$re)\s/, @arr1; print join("\n",@arr3),"\n";
