But if the dates are not the same I would like to copy o
Your code logic says that you want to find lines in '2.txt' that are NOT in
'1.txt'.
thanks for all answerers.

but the way mentioned by John, putting file's all contents to a hash,

hi,
Is there a best way to find some lines which exists in both two files?
Someone has show me a method but it seems a little low efficiency.
The code is as below:
open (T1,"1.txt") or die "$!";
open (T2,"2.txt") or die "$!";
while(my $line=){
chomp $line;
print $line,"\n" unless diff($line)
12 matches
