I can see a number of problems with your code ..
- The first time through the FILE2 loop, you'll read all of FILE1 and it will come up empty after that.
- You are reading all of FILE1 for each line of FILE2 -- that's not efficient.
- I would rename your array variables as array1 and array2 (corresponding, of course, to FILE1 and FILE2)
Second to last, I would reformat the code as:
open(FILE1, "$file1") || die "can't open file";
open(FILE2, "$file2") || die "can't open file";
while (<FILE2>)
{
chomp;
@array2= split;
while(<FILE1>)
{
chomp;
@array1 = split;
}
if ($array1[0] eq $array2[0])
{
print "match\n";
if ($array1[1] == $array[2])
{
print $array[1];
}
else
{
print " no match";
}
}
}
Finally, check out the other good responses to the original question .. your approach should be abandoned.
