premal: Note Also

Line 4 uses $file while line 1 has that var as $file1. Had you used strict and warnings you were have known this. But maybe it's merely a transcription typo; otherwise, contrary to your statement, you could *NOT* have "read the data from first file...."

As others noted, you should read perldoc -f open and use the three-arguement open described there.
