We defend the rights of all software users. The Bash command-line completion system is very flexible and customizable, and is often packaged with functions that complete arguments and filenames for specific programs and tasks.

Bash's syntax has many extensions lacking in the Bourne shell. Bash can perform integer calculations "arithmetic evaluation" without spawning external processes.

Because of these and other differences, Bash shell scripts are rarely runnable under the Bourne or Korn shell interpreters unless deliberately written with that compatibility in mind, which is becoming less common as Linux becomes more widespread.

Bash supports here documents. Since version 2. Bash 3. In February , [44] Bash 4. Bash 4 also switches its license to GPLv3 ; some users suspect this licensing change is why MacOS continues to use older versions.

Brace expansion, also called alternation, is a feature copied from the C shell. It generates a set of alternative combinations.

Generated results need not exist as files. The results of each expanded string are not sorted and left to right order is preserved:.

Users should not use brace expansions in portable shell scripts, because the Bourne shell does not produce the same output. When brace expansion is combined with wildcards, the braces are expanded first, and then the resulting wildcards are substituted normally.

In addition to alternation, brace expansion can be used for sequential ranges between two integers or characters separated by double dots.

Newer versions of Bash allow a third integer to specify the increment. When brace expansion is combined with variable expansion the variable expansion is performed after the brace expansion, which in some cases may necessitate the use of the eval built-in, thus:.

When Bash starts, it executes the commands in a variety of dot files. Unlike Bash shell scripts, dot files do not typically have execute permission enabled nor an interpreter directive like!

Bash calls these as part of its standard initialization, but other startup files can read them in a different order than the documented Bash startup sequence.

The default content of the root user's files may also have issues, as well as the skeleton files the system provides to new user accounts upon setup.

The startup scripts that launch the X window system may also do surprising things with the user's Bash startup scripts in an attempt to set up user-environment variables before launching the window manager.

If a piece of code uses such a feature, it is called a "bashism" — a problem for portable use. Debian's checkbashisms and Vidar Holen's shellcheck can be used to make sure that a script does not contain these parts.

Bash uses readline to provide keyboard shortcuts for command line editing using the default Emacs key bindings.

Vi-bindings can be enabled by running set -o vi. The Bash shell has two modes of execution for commands: batch , and concurrent mode. To execute commands in batch i.

Or to have a concurrent execution of two command1 and command2, they must be executed in the Bash shell in the following way:. A list of all processes, both in the background and stopped, can be achieved by running jobs :.

In the output, the number in brackets refers to the job id. The plus sign signifies the default process for bg and fg.

The text "Running" and "Stopped" refer to the Process state. The last string is the command that started the process.

The state of a process can be changed using various commands. The fg command brings a process to the foreground, while bg sets a stopped process running in the background.

Without one, they use the default process, identified by a plus sign in the output of jobs. The kill command can be used to end a process prematurely, by sending it a signal.

The job id must be specified after a percent sign:. Bash supplies "conditional execution" command separators that make execution of a command contingent on the exit code set by a precedent command.

For example:. Bash also supports if An external command called bashbug reports Bash shell bugs. When the command is invoked, it brings up the user's default editor with a form to fill in.

The form is mailed to the Bash maintainers or optionally to other email addresses. Bash programmable completion, complete and compgen commands [58] have been available since the beta version of 2.

Think of it as the opposite of Wine. While Wine allows you to run Windows applications directly on Linux, the Windows Subsystem for Linux allows you to run Linux applications directly on Windows.

Microsoft worked with Canonical to offer a full Ubuntu-based Bash shell environment that runs atop this subsystem. It now supports other Linux distributions, too.

There are some limitations here. You just need to install it from the Windows Features window. Instead, you have to install Ubuntu or another Linux distribution from the Store app.

This popular Linux distribution was previously the only option available, but other Linux systems are now available for people who have more specific needs.

You can even run multiple different Linux distributions at a time in different windows. Or you can use the web interface. Development of Bash, and GNU in general, is a volunteer effort, and you can contribute.
