diffindex-download - Download utility for Debian Contents files
SYNOPSIS
diffindex-download [ options ] URL filename
DESCRIPTION
diffindex-download is a command line tool for downloading Contents files. It uses APT's diff/Index format
patches when available to avoid downloading the full file. diffindex-download is used by apt-file.
OPTIONS
-n number
If more than number patches would be necessary, download the whole file. Specifying 0 to always
download the whole file is possible.
-k Don't verify the peer certificate when using https.
-c cacert
If cacert is a directory: Use cacert as CA certificate path. Otherwise use cacert as CA
certificate bundle. See the --capath and --cacert options in the curl(1) man page.
-i Don't exit with errror if the URL does not exist. This is useful as some archives don't provide
Contents files.
-q Be quiet (opposite of -v). The default if stdout is not a terminal.
-v Be verbose (opposite of -q). The default if stdout is a terminal.
-d Print additional debug info.
