Merging PDF skipping corrupted PDF by command line

Question: Currently I am using some application to merge a list of PDF which are downloaded. The issue is if any one of the PDF is corrupted, it stops the merging of the rest of the PDF.Is there any command line application which I can use to skip the corrupted PDF and merge the others? I have also tested with other software but facing the same issue.Or is there any other command line based PDF merging utility that I can use for this? Is there any solution on VeryPDF?
