in thread Combine files with same extension in new file

Thanks for answering me. yes as you said, it takes the output.txt file and run it as input. I added unlink 'output.txt'; before the "for my $file (glob '*.tsv')" as you said, but this time nothing happened and even did not make output.txt file. Thanks

    Wait, wait, wait... output.txt doesn't match *.tsv. Moreover, if the input files aren't in the current working directory, you have to specify their path, too:
    glob '/path/to/files/*.tsv'

      Sorry it is txt, I just make a mistake by typing and all my files in the same directory. Thanks
