NQUIRE(1)

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

SYNOPSIS
nquire [-help] [-ftp host dir [file]] [-url URL] [-get [URL]] [-len URL] [-lst host dir] [-dir host dir] [-eutils name] [-dwn host dir [file]] [-asp host dir [file]] [-ncbi|-eutils|-pubchem|-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.

-url URL
    Base URL for external search.

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

-len URL
    Content length of HTTP file.

-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.
