Re: print data with matching id from two different files

As you parse file2 you are neglecting to remove the quotes and the semi-colon, thus the key will never match.

Update: You aren't removing the leading "id " either. Are you sure those are tabs in your data?

Probably best to invoke item 2 from the Basic debugging checklist:

    my ($testKey, $name) = split("\t", $_);
    print "DEBUG: key is '$testKey', name is '$name'\n";

Please excuse me I forgot to mention that I removed semicolon and inverted commas using awk. So my written code is for a file3 without semicolon and inverted commas.Yes,there is tab in file3.	[reply]

In that case the likely problem is here: `open FILE3, "< file3" or die; while (<FILE2>) {` [download] As you can clearly see, you open FILE3 but try to read from FILE2 which is not opened. Running your code gives you this warning: `Name "main::FILE2" used only once: possible typo at 1202408.pl line 14.` which should have alerted you to this. Always address the warnings.
