Re^3: Combine files with same extension in new file

What do you mean? If I understand correctly, when you run it again, it finds output.txt created in the previous run as one of the inputs - that might be the problem. So, before doing glob,

unlink 'output.txt';

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	[reply]

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'` [download] لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]

This is great perl code to combine multiple files into one. After adding that extra line before GLOB, it work perfect!!! Thank you very much Choroba!! Roger	[reply]
