text: user982: Not sure if this is allowed but I cannot think of a better place to ask. I am attempting to download all genomic sequences from refseq associated with the query Peptostreptococcaceae. I have been been using the following command (based on some reading of the manual):
  esearch -db nuccore -query "Peptostreptococcaceae" | efilter -molecule genomic -source refseq | efetch -format fasta
  
  But I keep getting the following error

  user982: The issue here was I was using an older version of eDirect. There is no command to check version or updates. Your best bet is if you experience problems uninstall and reinstall. 
  
  user1810: If you want to find version info you can either :
  Ask for another edirect tool version (it will be the same version for edirect) :
  efetch -version
  
  
  6.80
  
  Check the info contained in the edirect.pl script :
  grep -i 'version = ' edirect.pl
  
  
  $version = "6.80";
