bcf file table output

[Giffredo]

Hi

I used mpileup.

samtools mpileup -f mi.fas sorted.bam&


samtools mpileup -f mi.fas sorted.bam | bcftools view > ed.vcf & 

I would to have a output like bam file or direct vcf file.
When I use the first command line, mpileup gives me directly the reults on the unix terminal window.
Using the second mpileup did not give me results at all..
