NAME

       nquire - query NCBI Entrez Utilities, other parameter-based web services, or FTP

SYNOPSIS

       nquire   [-help]   [-ftp host dir [file]]   [-get [fIURL]]   [-url URL]   [-lst host dir]  [-eutils name]
       [-dwn host dir [file]] [-asp host dir [file]] [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 [fIURL]
              Use HTTP(S) GET instead of POST.

       -url URL
              Base URL for external search.

       -lst host dir
              Lists contents of FTP site.

   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.

       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.)

       -examples
              Examples of advanced queries.

       -version
              Print version number.
