如何找到我使用 curl 命令下载的空文件？

Question

I executed curl command to retrieve, from the following webpage "http://files.rcsb.org/view/IDENTIFIER.pdb" the PDB files that have an identifier starting with 1W followed by any digit and ending with any upper case letter and save each into a separate file. But some of these files don't exist. My question is how to delete them.

I first run this command to download the files: curl http://files.rcsb.org/view/1W[0-9][AZ].pdb -o file_#1#2.txt

I got 260 files

enter image description here

What command should I run to remove empty files? Thank you!

Answer 1

As far as I know, the find command has a -delete parameter you can use. It also has has a -size parameter for filtering on size. The combination of both leads to this:

find ./ -type f -size 0 -delete

The URL, I refer to, gives some more background information and examples concerning the command.

Good luck
