Bash is a Unix shell and a form of command language first introduced in 1989. It has been widely used as a standard connection shell for Linux and MacOS. Although it is mainly seen under Linux and Marcos, there is a version that can be installed under Windows 10. However, many complaints have been received from users who cannot use Bash on Windows 10, and an error “Windows subsystem for Linux has no distributions installed” is displayed when you try to do so.

Manual installation of the distribution system

If some distributions cannot be downloaded and installed automatically, we can try to install them manually from the command line. Therefore, in this step, we will execute a command to install the large distributions. For that: read more

These script files were not developed for Windows and only work on Unix systems (Linux and MacOS, plus many others, less popular).

What is a .sh file?

Developer files known as scripts that the Bash application programs and uses. SH files are known to be created and stored in the Bash language because the instructions they contain are written in that language. SH files can be executed when text commands are entered in the shell command line interface. SH files are mainly used by program developers and these files are important for the Bash application because the application mainly uses scripts and commands that must be executed for this application to work. And since SH files are the scripts programmed with this application and contain the commands to run the program, they are indeed important. The commands contained in SH files vary, and the SH file extension is now developed into an interactive shell, although it is originally a scripting language. Programs such as C-Shell, Korn Shell and Bourne Shell also use SH files to store scripts. read more

PNG files (commonly called “ping”) are a format that contains bitmap or raster images. Originally, the PNG image format was created to adopt the GIF format, since both have the ability to display transparent backgrounds. Another similarity between the two is the use of indexed colors and lossless compression. However, PNG files do not have the same copyright restrictions. Unlike GIF images, files with the PNG extension do not support animation.

PNG and JPG (JPEG) formats are very popular. The best choice depends on your objectives. PNG uses lossless compression to maintain the best image quality. JPG uses lossy compression and high compression rates that significantly reduce the size of image files while maintaining good image quality. This compression is the reason why you might want a PNG to JPG converter, as it allows you to free up hard disk space. read more

RPM stands for Red Hat Package Manager. However, these days RPM isn’t only Red Hat specific because many other Linux distros use RPM for managing their software. For example, both Mandriva and SuSE use RPM for software management. With RPM, you can install, upgrade and uninstall software on Linux, as well as keep track of already installed RPM packages on your system. This can be done because RPM keeps a database of all software that was installed with it. read more

Have you ever wanted to run two or more sessions of the X Window System at the same time? Well, it is possible! You can have multiple X sessions running on different virtual terminals.

If your system is configured to start X automatically, you don’t have to worry about the first X session: it’s already running.

If you don’t have a graphical login, you probably start X with the startx command after logging in:
