How To Detect Overlaping Indels In Vcf File?

Hi all,

I have a vcf file with indels from a whole genome analysis and I want to detect overlapping between indels... I tried to use BEDtools-intersect but it asks for 2 files, and I only have a single file. Before trying the option of giving the same file 2 times to BEDtools-intersect maybe someone knows a better way or a better tool to achieve this.

Thanks!
