When logging into a Linux or Unix system, a login banner or message is displayed on the terminal. This banner usually contains system information or a warning to unauthorized users. While login banners are useful, they can be annoying or unnecessary in certain cases. In this guide, we will show you how to turn off the login banner in Linux and Unix using the hushlogin file.
Before we begin, ensure that you have the following prerequisites:
- A Linux or Unix system
- Root access to your system
- An internet connection
What is the Login Banner in Linux or Unix?
When you log in to your Linux or Unix system using ssh or other methods, you may see a lot of information on your screen. This information is commonly known as the login banner. The banner typically displays system information, including the system load, disk usage, memory usage, and other statistics.
What is the .hushlogin File in Linux or Unix?
The .hushlogin file is an individual file that can be created in your login directory ($HOME). This file is used to suppress the display of the login banner for individual users. By creating a new empty .hushlogin file in your login directory, you can turn off the login banner for your user account.
