I have downloaded sratoolkit for ubuntu. After getting the tar file and unzip it, I added the bin path to the Path variables as well. When I run which fastq-dump, it correctly identifies the path. However, when I run vdb-config -i or vdb-config --interactive nothing happens. It is the same with other commands. When I look into the directory, most of the files have zero byte. I have vdb-config with zero byte, vdb-conifg.3 with zero byte, and vdb-config.3.0.1 with 6,110 KB. What do these mean?
Does this mean I should run vdb-config.3.0.1 -i?
Sorry, if I am asking naive question.
