SYNOPSIS

       nquire    [-help]    [-ftp host dir [file]]    [-get [URL]]   [-url URL]   [-lst host dir]
       [-dir host dir]     [-eutils name]      [-dwn host dir [file]]      [-asp host dir [file]]
       [-ncbi|-eutils|-pugrest|-pugview] [component ...] [-tag value ...] [-examples] [-version]

DESCRIPTION

       nquire  performs  raw  HTTP(S)  queries against web services such as NCBI E-Utilities that
       take GET or POST parameters, or  downloads  or  listings  from  FTP  and  Aspera  servers.
       (Aspera support requires installing proprietary client software.)

OPTIONS

   Documentation
       -help  Print   usage   information,  complete  with  a  few  examples,  some  additionally
              illustrating the use of xtract(1).

   Query Commands
       -ftp host dir [file]
              Use FTP instead of HTTP.  The  shell  implementation  accepts  a  filename  on  the
              command  line  only  when  invoked  from  a  (pseudo)terminal,  and otherwise reads
              filenames from standard input.

       -get [URL]
              Use HTTP(S) GET instead of POST.

       -url URL
              Base URL for external search.

       -lst host dir
              Lists contents of FTP site.

       -dir host dir
              FTP listing with file sizes.

   File Downloads
       -dwn host dir [file]
              Like -ftp, but saves  contents  to  correspondingly  named  files  in  the  current
              directory.

       -asp host dir [file]
              Like -dwn, but uses Aspera's proprietary client if installed.

   -url Shortcuts
       -ncbi     https://www.ncbi.nlm.nih.gov

       -eutils   https://eutils.ncbi.nlm.nih.gov/entrez/eutils

       -pugrest  https://pubchem.ncbi.nlm.nih.gov/rest/pug

       -pugview  https://pubchem.ncbi.nlm.nih.gov/rest/pug_view

   URL Additions
       component
              Add /component to the base URL.  (Must precede any tag/value pairs.)

       -tag value ...
              Add &tag=value,... to the base URL.  (Must follow any simple components.)

   Miscellaneous
       -examples
              Examples of advanced queries.

       -version
              Print version number.
