This article will explain in detail what linux bash refers to. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Bash (GNU Bourne-Again Shell) is the default Shell for many Linux distributions. In fact, there are many Shell used on traditional UNIX, such as tcsh, csh, ash, bsh, ksh, etc., Shell Script is roughly the same, when you learn one kind of Shell, other Shell will be used quickly, most of the time, a Shell Script can usually be used on many kinds of Shell.

Bash is the default shell of most Linux systems and Mac OS X. It can run on most Unix-like operating systems, and it has even been transplanted to the Cygwin system on Microsoft Windows to implement the POSIX virtual interface of Windows. In addition, it has also been ported to MS-DOS by the DJGPP project.

Bash's command syntax is a superset of Bourne shell command syntax. Most of the large number of Bourne shell scripts can be executed in bash without modification, and only scripts that use special variables or built-in commands of Bourne need to be modified.

Many of bash's command syntax comes from Korn shell (ksh) and C shell (csh), such as command line editing, command history, directory stack, $RANDOM and $PPID variables, and POSIX's command replacement syntax: $(...). As an interactive shell, press the TAB key to automatically complete partially entered program names, file names, variable names, and so on.

So much for sharing what linux bash refers to. I hope the above content can be helpful to everyone and learn more knowledge. If you think the article is good, you can share it for more people to see.
