Hallow, every one

when I use eprimer3 to generate primers for fasta sequence of sars cov 2 whole genome give Error:

Argument 'saracovII.fasta' : Too many parameters 3/2

what the best way to write eprimer3 command line to generate primers I used this command

eprimer3 -outfile=out.pr3 -sequence= saracovII.fasta

Thanks for your attention
