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

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.)

              xtract(1).

   QueryCommands-ftphostdir [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.

       -urlURL
              Base URL for external search.

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

       -lenURL
              Content length of HTTP file.

       -lsthostdir
              Lists contents of FTP site.

       -dirhostdir
              FTP listing with file sizes.

   FileDownloads-dwnhostdir [file]
              Like -ftp, but saves contents to correspondingly named files in the current directory.

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