.SH SYNOPSIS
.B ddgr [OPTIONS] [KEYWORD [KEYWORD ...]]
.SH DESCRIPTION
.B ddgr
is a command-line tool to search DuckDuckGo (html version). \fBddgr\fR shows the title, URL and text context for each result. Results are fetched in pages. Keyboard shortcuts are available for page navigation. Results are indexed and a result URL can be opened in a browser using the index number. There is no configuration file as aliases serve the same purpose for this utility. Supports sequential searches in a single instance.

.SH OPTIONS
.TP
.BI "-h, --help"
Show help text and exit.
.TP
.BI "-n, --num=" N
Show N results per page (default 10). N must be between 0 and 25. N=0 disables fixed paging and shows actual number of results fetched per page.
.TP
.BI "-r, --reg=" REG
Region-specific search e.g. 'us-en' for US (default); visit https://duckduckgo.com/params.
.TP
.BI "-C, --nocolor"
Disable color output.
.TP
.BI "--colors=" COLORS
Set output colors. Refer to the \fBCOLORS\fR section below for details.
.TP
.BI "-j, --ducky"
Open the first result in a web browser; implies \fB--noprompt\fR. Feeling Ducky?
.TP
.BI "-t, --time=" SPAN
Time limit search [d=past day, w=past week, m=past month, y=past year] (default=any time).
.TP
.BI "-w, --site=" SITE
Search a site using DuckDuckGo.
.TP
.BI "-x, --expand"
Expand URLs instead of showing only the domain name (default).
.TP
.BI "-p, --proxy=" URI
Tunnel traffic through an HTTP proxy. \fIURI\fR is of the form \fI[http[s]://][user:pwd@]host[:port]\fR. The proxy server must support HTTP CONNECT tunneling and must not block port 443 for the relevant DuckDuckGo hosts. If a proxy is not explicitly given, the \fIhttps_proxy\fR or \fIHTTPS_PROXY\fR environment variable (if available) is used instead.
.TP
.BI "--unsafe"
Disable safe search.
.TP
.BI "--noua"
Disable user agent. Results are fetched faster.
.TP
.BI "--json"
Output in JSON format; implies \fB--noprompt\fR.
.TP
.BI "--gb, --gui-browser"
Open a bang directly in a GUI browser.
.TP
.BI "--np, --noprompt"
Perform search and exit; do not prompt for further interactions.
.TP
.BI "--rev, --reverse"
List the entries in reversed order.
.TP
.BI "--url-handler=" UTIL
Custom script or command-line utility to open urls with.
.TP
.BI "--show-browser-logs"
Do not suppress browser output when opening result in browser; that is, connect stdout and stderr of the browser to ddgr's stdout and stderr instead of /dev/null. By default, browser output is suppressed (due to certain graphical browsers spewing messages to console) unless the \fBBROWSER\fR environment variable is a known text-based browser: elinks, links, lynx, w3m or www-browser.
.TP
.BI "-v, --version"
Show version number and exit.
.TP
.BI "-d, --debug"
Enable debugging.

Open space-separated result indices, numeric ranges or all indices, if 'a' is specified, in the browser.

Works similar to key 'o', but tries to ignore text-based browsers (even if BROWSER is set) and open links in a GUI browser.
