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.
