DESCRIPTION

       edirect   (Entrez  Direct)  is  a  command-line  utility  for  consulting  NCBI's  set  of
       interconnected databases (publication, sequence, structure, gene,  variation,  expression,
       etc.)   in  a variety of fashions, each of which is documented individually in a dedicated
       man page.

COMMON OPTIONS

       Most subcommands accept the following options, in addition to command-specific options.

       -help  Print usage information.

       -email address
              Send the given e-mail address to have someone to notify in case  a  runaway  script
              causes problems with an NCBI Entrez server.

       -tool name
              Send the given client name.

       -http[s] get
              Force the use of GET rather than POST HTTPS requests.

       -alias filename
              Specify a file of shortcut keywords and query strings or URL sections.

       -silent
              Suppress connection failure retry messages.

       -verbose
              Display the ENTREZ_DIRECT XML field values at each step.

       -debug Print the internal URL query and XML results of each step.

       -base URL
              Specify a particular server for quality assurance testing.

ENVIRONMENT

       EDIRECT_DO_AUTO_ABBREV
              Accept (currently) unambiguous truncated option names, as in -verbo for -verbose.

       NCBI_API_KEY
              NCBI  E-Utilities  API  key, allowing for a higher request rate at the cost of some
              anonymity.
