BLAST error: Too many positional arguments

BLAST software tool

blastn –db nt –query nt.fsa –out results.out

Error: Too many positional arguments (1), the offending value

Problem is a copy & past from the BLAST documentation, all dashes ('') need to be replaced by hand at the command line.

Replace / re-type all '–' with '-'

blastn -db nt -query nt.fsa -out results.out
