A user agent is a computer program representing a person, for example, a browser in a Web context.
Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.
Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.
A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

If you need to integrate the user agent parser directly into your website or system then it's very simple to use the API. This will let you do things like advanced filtering and searching, identify trends in user agents, perform statistical analysis and other interesting applications.

This morning, we thought we had a little time to do something fun, and so we created a command to generate a list of all user agent strings (or signatures) on a very high traffic Joomla website that we maintain.
…sorts the list returned by the previous command by number of occurrences of user agent strings descending. …removes the first column (which contains the number of occurrences of each user agent string).
…returns the first 500 lines (e.g. the top 500 user agent strings, ordered by number of occurrences, descending). If you decide to run the above set of commands, then please keep in mind that it will take about 10-15 minutes to process a 10 GB log file even when using a relatively powerful server with an SSD drive.
That can be a hard thing to do if you only know a handful of user agents. Not to mention building your own comprehensive list of user agent strings takes time.

It was the first browser to actually implement images embedded in the text, rather than displayed in a separate window. Mosaic was developed at the National Center for Super computing Applications (NASA) beginning in late 1992.
NASA released the browser in 1993, and officially discontinued development and support on January 7, 1997. Here is a working list of all user agents for the major, top search engines.
Having the user agents for these popular bots all in one place helps to streamline my development process. Each search engine includes references and a regex pattern to match all known user agents.
