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 | -datasets ] [ 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.
