Although there exist other better shells, bash is considered as the defacto standard shell on Linux distributions. In particular, only the kernel is a Linux. The base provides a collection of utilities or the GNU Unix environment. For this reason, bash is the default shell for Linux distributions.
Bash is universal since it has a variety of features that are not found on other shells. Moreover, it incorporates the essential characteristics of Korn-shell and C-shell (Johnson & Varma, 2015). Bash involves the implementation of Bourne Shell, which comprises features such as job control, shell history, and command-line completion. On that note, the combination of bash with other shells in Linux distributions depicts its compatibility that facilitates scalability and the provision of appealing features to developers (Makan, 2014). Consequently, bash offers a user-friendly programming interface, which is why many software developers prefer using it.

Another reason why bash is the default shell for Linux distributions is that it gets consistent updates and new advanced features. Specifically, it continues to develop and evolve such that it satisfies users’ requirements making it more attractive. For example, bash has many shortcuts that cannot be found in other shells. Linux administrators complete their jobs quickly since they can use various methods to get similar outcomes (Mary, 2015). Therefore, it is difficult for someone who has been using bash to work with other shells. Bash is recommendable for amateur, advanced, and professional Linux users. Overall, this shell allows administrators to get things done quickly.
To conclude, bash is the defacto standard shell on Linux distributions. In essence, it is universally accepted and compatible with other shells such as Korn-shell. Bash gets consistent updates and new advanced features since it is a part of the GNU system. Most importantly, it has many shortcuts that enable developers to multitask.
