How to Use the Command 'googler' (with Examples)
Googler is a command-line tool that allows users to search Google directly from their terminal. This versatile tool brings the powerful capabilities of Google’s search engine into the hands of command-line enthusiasts, developers, and those who prefer working outside a traditional web browser. Googler is especially useful for quickly accessing Google search results, opening links in browsers, and managing searches in various formats and settings.
Use Case 1: Search Google for a Keyword
Code:
googler keyword
Motivation:
Using the command line to search Google can be a boon for individuals who work extensively in terminal environments or want to avoid the distractions that come with web browsers. Whether you’re a developer looking for documentation or a researcher gathering information, executing a quick search for a keyword is efficient and straightforward.
Explanation:
googler: This is the program or command name which initiates the search process.keyword: This is the argument for the search. It is the query you’re interested in finding information about. When you run this command, Googler sends the keyword to Google and retrieves search results.
Example Output:
1: Wikipedia - Keyword
2: Dictionary.com - Definition of Keyword
3: News about Keyword
The command will fetch relevant links based on the keyword, typically displaying the top results you’d see in a standard Google search.
Use Case 2: Search Google and Open the First Result in Web Browser
Code:
googler -j keyword
Motivation:
Sometimes, a user knows precisely what kind of information they are expecting. In such cases, the first search result might be the one they need. This command is perfect for those who want to streamline the process of searching and accessing information, reducing the steps needed to open the desired page in a web browser.
Explanation:
-j: This flag stands for “jump” and instructs Googler to open the first result in the default web browser automatically.keyword: This remains the search query you wish to look up.
Example Output:
Opening the first result for 'keyword' in web browser.
After running this command, your default web browser launches and opens the first link returned by Googler, simplifying the process from search to discovery.
Use Case 3: Show N Search Results (Default 10)
Code:
googler -n 5 keyword
Motivation:
While the default number of search results displayed is 10, a user might need fewer results for a quick review or more for detailed research. Customizing the number of displayed results makes it easier to consume information in manageable chunks according to one’s needs, particularly if the terminal window is small or if specific information is being targeted.
Explanation:
-n 5: This option allows you to specify the number of search results that will be displayed. Here, ‘5’ is an example number, but it can be set to any number suited to your requirements.keyword: This is the search query for which you’re fetching results.
Example Output:
1: First result for 'keyword'
2: Second result for 'keyword'
3: Third result for 'keyword'
4: Fourth result for 'keyword'
5: Fifth result for 'keyword'
The terminal displays the specified number of results, allowing efficient use of space and time.
Use Case 4: Disable Automatic Spelling Correction
Code:
googler -x keyword
Motivation:
Google often auto-corrects query terms for better search results. However, this may not always be desirable, especially when searching for uniquely spelled brands, scientific terms, or regional terms. Keeping Google’s automatic correction from interfering can ensure that the results remain true to the original input.
Explanation:
-x: This option disables the automatic spelling correction offered by Google.keyword: This is the search term you are entering.

Use Case 5: Search One Site for a Keyword
Code:
googler -w site.com keyword
Motivation:
Searching within a particular website is often required when one needs information from a known, trusted source. This is useful for developers seeking documentation from sites like MDN or academics looking for journals on specific sites. This command focuses the search on the specified domain.
Explanation:
-w site.com: This flag allows you to narrow your search exclusively to the specified website. Replace ‘site.com’ with your target website.keyword: This remains the search query focused on within the given site.
Example Output:
Results for 'keyword' on 'site.com':
1: Relevant page on site.com
2: Related article on site.com
By restricting the search to a single domain, users can efficiently hone in on results from a specific source.
Use Case 6: Show Google Search Result in JSON Format
Code:
googler --json keyword
Motivation:
Getting results in JSON format is beneficial for developers and data analysts who might want to parse and process search results programmatically. JSON format standardizes the output in a way that is easily ingested by scripts or systems for further analysis or automation.
Explanation:
--json: This option changes the output format of the search results into JSON, suited for further processing.keyword: This is the search term you’re querying.
Example Output:
[
{"title": "First result", "url": "http://example.com/1", "snippet": "Description of first result"},
