googler is a power tool to Google (Web & News) and Google Site Search from the command-line. It shows the title, URL and abstract for each result, which can be directly opened in a browser from the terminal. Results are fetched in pages (with page navigation). Supports sequential searches in a single googler instance.

googler was initially written to cater to headless servers without X. You can integrate it with a text-based browser. However, it has grown into a very handy and flexible utility that delivers much more. For example, fetch any number of results or start anywhere, limit search by any duration, define aliases to google search any number of websites, switch domains easily… all of this in a very clean interface without ads or stray URLs. The shell completion scripts make sure you don’t need to remember any options.

googler isn’t affiliated to Google in any way.

Installation

Dependencies

googler requires Python 3.5 or later. Only the latest patch release of each minor version is supported.

To copy url to clipboard at the omniprompt, googler looks for xsel or xclip or termux-clipboard-set (in the same order) on Linux, pbcopy (default installed) on macOS and clip (default installed) on Windows. It also supports GNU Screen and tmux copy-paste buffers in the absence of X11.

From a package manager

Install googler from your package manager. If the version available is dated try an alternative installation method.

Tips for packagers

googler v2.7 and later ships with an in-place self-upgrade mechanism which you may want to disable. To do this, run

$ make disable-self-upgrade

before installation.

Release packages

Packages for Arch Linux, CentOS, Debian, Fedora, openSUSE and Ubuntu are available with the latest stable release.

From source

If you have git installed, clone this repository. Otherwise download the latest stable release or development version.

To install to the default location (/usr/local):

$ sudo make install

To remove googler and associated docs, run

$ sudo make uninstall

PREFIX is supported, in case you want to install to a different location.

Running standalone

googler is a standalone executable (and can run even on environments like Termux). From the containing directory:

$ ./googler

Downloading a single file

googler is a single standalone script, so you could download just a single file if you’d like to.

To install the latest stable version, run

$ sudo curl -o /usr/local/bin/googler https://raw.githubusercontent.com/jarun/googler/v4.0/googler && sudo chmod +x /usr/local/bin/googler

You could then let googler upgrade itself by running

$ sudo googler -u

Similarly, if you want to install from git master (risky), run

$ sudo curl -o /usr/local/bin/googler https://raw.githubusercontent.com/jarun/googler/master/googler && sudo chmod +x /usr/local/bin/googler

and upgrade by running

$ sudo googler -u --include-git

Shell completion

Search keyword and option completion scripts for Bash, Fish and Zsh can be found in respective subdirectories of auto-completion/. Please refer to your shell’s manual for installation instructions.

Configuration file

googler doesn’t have any! This is to retain the speed of the utility and avoid OS-specific differences. Users can enjoy the advantages of config files using aliases (with the exception of the color scheme, which can be additionally customized through an environment variable; see Colors). There’s no need to memorize options.

For example, the following alias for bash/zsh/ksh/etc.

alias g='googler -n 7 -c ru -l ru'

fetches 7 results from the Google Russia server, with preference towards results in Russian.

The alias serves both the purposes of using config files:

  • Persistent settings: when the user invokes g, it expands to the preferred settings.
  • Override settings: thanks to the way Python argparse works, googler is written so that the settings in alias are completely overridden by any options passed from cli. So when the same user runs g -l de -c de -n 12 hello world, 12 results are returned from the Google Germany server, with preference towards results in German.

googler @t

googler @t is a convenient add-on to Google Site Search with unique keywords. While googler has an integrated option to search a site, we simplified it further with aliases. The file googler_at contains a list of website search aliases. To source it, run:

$ source googler_at

or,

$ . googler_at

With googler @t, here’s how you search Wikipedia for hexspeak:

$ @w hexspeak

Oh yes! You can combine other googler options too! To make life easier, you can also configure your shell to source the file when it starts.

All the aliases start with the @ symbol (hence the name googler @t) and there is minimum chance they will conflict with any shell commands. Feel free to add your own aliases to the file and contribute back the interesting ones.

Text-based browser integration

googler works out of the box with several text-based browsers if the BROWSER environment variable is set. For instance,

$ export BROWSER=w3m

or for one-time use,

$ BROWSER=w3m googler query

Due to certain graphical browsers spewing messages to the console, googler suppresses browser output by default unless BROWSER is set to one of the known text-based browsers: currently elinks, links, lynx, w3m or www-browser. If you use a different text-based browser, you will need to explicitly enable browser output with the --show-browser-logs option. If you believe your browser is popular enough, please submit an issue or pull request and we will consider whitelisting it. See the man page for more details on --show-browser-logs.

If you need to use a GUI browser with BROWSER set, use the omniprompt key O. googler will try to ignore text-based browsers and invoke a GUI browser. Browser logs are always suppressed with O.

Colors

googler allows you to customize the color scheme via a six-letter string, reminiscent of BSD LSCOLORS. The six letters represent the colors of

  • indices
  • titles
  • URLs
  • metadata/publishing info (Google News only)
  • abstracts
  • prompts

respectively. The six-letter string is passed in either as the argument to the --colors option, or as the value of the environment variable GOOGLER_COLORS.

We offer the following colors/styles:

Letter Color/Style
a black
b red
c green
d yellow
e blue
f magenta
g cyan
h white
i bright black
j bright red
k bright green
l bright yellow
m bright blue
n bright magenta
o bright cyan
p bright white
A-H bold version of the lowercase-letter color
I-P bold version of the lowercase-letter bright color
x normal
X bold
y reverse video
Y bold reverse video

The default colors string is GKlgxy, which stands for

  • bold bright cyan indices
  • bold bright green titles
  • bright yellow URLs
  • cyan metadata/publishing info
  • normal abstracts
  • reverse video prompts

Note that

  • Bright colors (implemented as \x1b[90m\x1b[97m) may not be available in all color-capable terminal emulators;
  • Some terminal emulators draw bold text in bright colors instead;
  • Some terminal emulators only distinguish between bold and bright colors via a default-off switch.

Please consult the manual of your terminal emulator as well as the Wikipedia article on ANSI escape sequences.

Domain-only URL

To show the domain names in search results instead of the expanded URL (and use lesser space), set the environment variable DISABLE_URL_EXPANSION.

Examples

  1. Google hello world:

    $ googler hello world
    
  2. Fetch 15 results updated within the last 14 months, starting from the 3rd result for the keywords jungle book in site imdb.com:

    $ googler -n 15 -s 3 -t m14 -w imdb.com jungle book
    
  3. Read recent news on gadgets:

    $ googler -N gadgets
    
  4. Fetch results on IPL cricket from Google India server in English:

    $ googler -c in -l en IPL cricket
    
  5. Search quoted text:

    $ googler it\'s a \"beautiful world\" in spring
    
  6. Search for a specific file type:

    $ googler instrumental filetype:mp3
    
  7. Disable automatic spelling correction, e.g. fetch results for googler instead of google:

    $ googler -x googler
    
  8. I’m feeling lucky search:

    $ googler -j leather jackets
    
  9. Website specific search:

    $ googler -w amazon.com -w ebay.com digital camera
    

    Site specific search continues at omniprompt.

  10. Alias to find definitions of words:

    alias define='googler -n 2 define'
    
  11. Look up n, p, o, O, q, g keywords or a result index at the omniprompt: as the omniprompt recognizes these keys or index strings as commands, you need to prefix them with g, e.g.,

    g n
    g g keywords
    g 1
    
  12. Input and output redirection:

    $ googler -C hello world < input > output
    

    Note that -C is required to avoid printing control characters (for colored output).

  13. Pipe output:

    $ googler -C hello world | tee output
    
  14. Use a custom color scheme, e.g., a warm color scheme designed for Solarized Dark (screenshot):

    $ googler --colors bjdxxy google
    $ GOOGLER_COLORS=bjdxxy googler google
    
  15. Tunnel traffic through an HTTPS proxy, e.g., a local Privoxy instance listening on port 8118:

    $ googler --proxy localhost:8118 google
    

    By default the environment variable https_proxy is used, if defined.

  16. Quote multiple search keywords to auto-complete (using completion script):

    $ googler 'hello w<TAB>
    
  17. More help:

    $ googler -h
    $ man googler
    

Troubleshooting

  1. In some instances googler may show fewer number of results than you expect, e.g., if you fetch a single result (-n 1) it may not show any results. The reason is Google shows some Google service (e.g. Youtube) results, map locations etc. depending on your geographical data, which googler tries to omit. In some cases Google (the web-service) doesn’t show exactly 10 results (default) on a search. We chose to omit these results as far as possible. While this can be fixed, it would need more processing (and more time). You can just navigate forward to fetch the next set of results.

  2. By default googler applies some TCP optimizations and forces TLS 1.2 (on Python 3.4 and above). If you are facing connection issues, try disabling both using the --notweak switch.

  3. Google News service is not available if the language is dk (Denmark), fi (Finland) or is (Iceland). Use -l en. Please refer to #187 for more information.

  4. Some users have reported problems with a colored omniprompt (refer to issue #203) with iTerm2 on macOS. To force a plain omniprompt:

    export DISABLE_PROMPT_COLOR=1
    

Notes

  1. Initially I raised a pull request but I could see that the last change was made 7 years earlier. In addition, there is no GitHub activity from the original author Henri Hakkinen in past year. I have created this independent repo for the project with the name googler. I retained the original copyright information (though googler is organically different now).

  2. Google provides a search API which returns the results in JSON format. However, as per my understanding from the official docs, the API issues the queries against an existing instance of a custom search engine and is limited by 100 search queries per day for free. In addition, I have reservations in paying if they ever change their plan or restrict the API in other ways. So I refrained from coupling with Google plans & policies or exposing my trackable personal custom search API key and identifier for the public. I retained the browser-way of doing it by fetching html, which is a open and free specification.

  3. You can find a rofi script for googler here. Written by an anonymous user, untested and we don’t maintain it.

  4. The Albert Launcher python plugins repo (awesome-albert-plugins) includes suggestions-enabled search plugins for a variety of websites using googler. Refer to the latter for demos and usage instructions.
