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.)

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.
