fpaste – A Tool for Sharing Errors and Commandline Output to Pastebin

Software developers or users always encounter different problems during the process of software development or usage. Some of these problems may include errors, therefore one way to solve them is to share error messages, command output or the contents of given files with other developers or users on the Internet.

There are many online platforms for sharing such problems which can be referred to as online content-sharing tool. An online content-sharing tool is often called a pastebin.

The Fedora ecosystem has one such tool called fpaste, is a web-based pastebin and a command line tool used for debugging errors or simply looking for feedback on some text.

Therefore in this article we are going to look at ways of how you can use fpaste as a programmer or normal user to report errors from commandline to fpaste.org site..

In order to use fpaste, you need to access it using one of the two ways; via the website or the command line. In this guide we shall focus more on the command line but let us see how you can use it via the web-based interface.

To use it from the website, you can go to fpaste website, copy your error, paste it into the input box provided, and then submit it. A response page will be provided and it has the URL link that you can send to fellow debuggers.

The web user interface allows a user to:

  1. set the syntax of the paste.
  2. tag the paste with his or her alias.
  3. use a password.
  4. set a time for the pasted error to expire.
