Zsh (Z Shell) is a Unix shell and command language that can be used as an interactive login shell and as a powerful command line interpreter for scripting. It provides a number of features that are not available in the Bourne shell (sh), such as extended globbing, spelling correction, and more.
Zsh is a Unix shell that is similar to the Bourne shell (sh), but with more powerful features such as extended globbing, spelling correction, and improved tab completion. It is highly configurable, and can be used as an interactive login shell or as a powerful command line interpreter for scripting.
Zsh is built on top of the Bourne shell, so it is compatible with sh scripts. It also provides a number of features that are not available in sh, such as job control, command line editing, and more. Zsh also supports many scripting languages, including bash, ksh, and csh.
Zsh is highly configurable, and can be customized to suit the user's needs. It has many options that can be used to customize the prompt, command line completion, aliases, and more. It also provides a number of plugins and themes that can be used to further customize the shell.
Zsh provides a number of features that make it a powerful and versatile shell. Some of these features include:
Extended globbing: Zsh supports extended globbing, which allows for more powerful pattern matching and wildcard expansion.
Spelling correction: Zsh can automatically correct spelling mistakes in commands.
Command line editing: Zsh provides an advanced command line editor, which allows users to easily edit and manipulate their commands.
Tab completion: Zsh provides an advanced tab completion system, which can be used to quickly complete commands.
Job control: Zsh supports job control, which allows users to run multiple commands simultaneously.
Aliases: Zsh supports aliases, which allow users to create shortcuts for commonly used commands.
Scripting languages: Zsh supports a number of scripting languages, including bash, ksh, and csh.
Here is an example of how to use Zsh to create a simple alias. In this example, we will create an alias for the ls
command that will list the contents of the current directory in long format:
$ alias lsl="ls -l"
Now, when we type lsl
at the command prompt, Zsh will run the ls -l
command, which will list the contents of the current directory in long format.
