$ ddgr -w ostechnix.com arch linux

The above command will return results related to arch linux in ostechnix.com.

Display complete URLs

As you may noticed in the above outputs, ddgr displays only the domain names for all search results. If you want ddgr to show you the complete URLs instead of just domain name, use -x flag.

$ ddgr -x arch linux

Display complete URLs in search results using ddgr

Search for quoted text

When you want to search for some exact texts, for example song lyrics or quotes of a famous author, just mention them inside quotes like below.

$ ddgr "You have to dream before the dream comes true"

Search for specific file type

This tip will be useful when searching for a specific type of a file to download, for example a song, video, movie or text or pdf file.

$ ddgr blockchain filetype:pdf

The above command will fetch results related to Blockchain documents in pdf format.

Limit number of searches per page

You can limit the number of search results per page you'd like to see in ddgr interface.

For instance, to display only 3 results for the given query, run:

$ ddgr -n 3 ostechnix

Display results within a specific time span

Display results updated within the last 1 month for the keyword linux in ostechnix.com site:

$ ddgr -t m 1 linux -w ostechnix.com

Fetch region-specific results

If you want ddgr to fetch search results exclusively from a certain region, use -r flag.

$ ddgr -r in-en best smartphone

This will return results from India server for best smartphone query. Visit https://duckduckgo.com/params to find your region parameter.

I'm feeling Lucky search

To perform "I'm Feeling Lucky" search, use -j flag followed by your search term as shown below.

$ ddgr -j browse web with vim keybindings

This command will directly load the first search result in your default browser.

DuckDuckGo Bangs

DuckDuckGo bangs allows you to search directly on your favorite websites and blogs, without having to visit them first. Bangs are just shortcuts that quickly take you to search results on other sites.

To perform a DuckDuckGo Bang search, run:

$ ./ddgr \!ostech linux

The above command will directly take you to ostechnix.com blog and display the results related to “linux” search term. Bangs will work at the omniprompt as well.

To learn more about Bangs, refer the following link.

Disable Safe search

Unlike Google, DuckDuckGo will filter contents from adult/porn websites by default. If you want to disable the Safe search feature, use:

$ ddgr --unsafe <search-term>

Display IP address

To display your public IP address in the Terminal using ddgr, run:

$ ddgr -n 1 --np ip

Integrate ddgr with Text browsers

We can integrate ddgr with several Text-browsers such as elinks, links, lynx and w3m or www-browser. ddgr will work out of the box with the text browsers if the BROWSER environment variable is correctly set.

For example:

$ export BROWSER=w3m

For one-time use,

$ BROWSER=w3m ddgr dns

Or, do site-specific search:

$ BROWSER=w3m ddgr -w ostechnix.com arch linux

This command will search for arch linux query in ostechnix.com. When you type the index number of any link and hit ENTER key, it will open in w3m browser by default.

To make it permanent, add the BROWSER environment variable in ~/.bashrc file.

$ echo “export BROWSER=w3m” >> ~/.bashrc

Getting help

To view the list of all supported options along with description, run:

$ ddgr --help

Or, shortly:

$ ddgr -h

You can also press the ? (question mark) to view the instant help section:

ddgr (? for help) ?

omniprompt keys:
  n, p, f               fetch the next, prev or first set of search results
  index                 open the result corresponding to index in browser
  o [index|range|a ...] open space-separated result indices, ranges or all
  O [index|range|a ...] like key 'o', but try to open in a GUI browser
  d keywords            new DDG search for 'keywords' with original options
                        should be used to search omniprompt keys and indices
  x                     toggle url expansion
  c index               copy url to clipboard
  q, ^D, double Enter   exit ddgr
  ?                     show omniprompt help
  *                     other inputs are considered as new search keywords
