Zsh change prompt

At the simplest level, a shell is a program that allows you to control a computer, in this case, a Mac, using commands you enter with the keyboard. Shells are usually interactive text-based interfaces that accept commands and present the results. In those early days, controlling a computer was a daunting task that could require you to manually load memory locations, one at a time, with the data that would eventually be run as a program. In some cases, this was done by setting a row of switches that represented a memory location address, and then loading data into the memory with another set of switches.

This process was labor-intensive and prone to errors. In many cases, the manually loaded program was for a boot loader that allowed the computer to accept input from a paper tape reader. Once the paper tape reader was operational, you could load a shell program that allowed a Teletype to be used as a command line interface.

Ah, those were the days. Using a shell and a command line was a lot easier for working with a computer than rows and rows of toggle switches. OK, so the shell was a big improvement back then, but why is it still used today with modern computers?

And like most Unix or Linux based systems, the command line interface is one of the key methods for interacting with the operating system. The Mac and many UNIX and Linux systems also features a graphical user interface to make working with the computer even easier.

But the command line still exists, and for working with core components of the operating system it can be very versatile, providing more capabilities than what is available in the GUI Graphical User Interface. The shell controls how the command line is presented to the user and what features the command line supports. Most shells offer the following to some degree or other:. Apple is changing from the Bash shell to the Zsh Z Shell. To put that in perspective, the version of Bash used on your Mac was new when the first iPhone was introduced.

The Zsh included with macOS Catalina is version 5. Yes, and no. Apple will set the Zsh as the default for any new user account that is created in macOS Catalina or later. If you upgraded your Mac from an earlier version of the macOS, then those existing user accounts are still using the Bash shell. You are, however, free to upgrade all accounts to Zsh, or downgrade an account to Bash or for that matter, to any shell you wish to use.

Not very; Bash and Zsh have a very high level of compatibility between them. Both are based on the older Bourne shell.This may be confusing, so here is the summary of what we will be doing. A lot of programmers like ITerm2 instead of the default Terminal. It is similar to the Terminal, but has lots of features of its own. It of course can run ZSH, Bash, and other shells inside it. To use it, all we need to do is to change shell chsh. This option is pretty common among users, because some of the plugins only work with the latest ZSH.

Homebrew, simply said, is a command line installer for all sorts of software. So make sure to install the Xcode CLI tools by running the following command. Run the following command to install ZSH. It should look something like below.

PS: But some Themes need extra steps like installing specific fonts and so on. This is a popular theme because it emulates the Powerline Python app that enhances the terminal.

The following picture shows how it looks. But this theme also needs us to install Powerline themes. Install Powerline fonts. You can set any Powerline patched font you like. There are plenty of gorgeous color schemes for iTerm2. These schemes change the foreground color, background color, cursor color, and so on.

You can find them at iTerm2-color-schemes Github repo. Plugins add more functionalities to your workflow.I spend a lot of time in a Terminal window at a command line. Up until about a month ago I was using bash for my shell. I decided to try switching to Zsh after hearing a lot of good things about it and I'm very happy with the change. A few days ago I tweeted my current Zsh prompt and the general response was: "Cool, but how did you do it? One quick note: This entry is about the prompt that I find useful.

You are not me, so you'll almost certainly have different needs. That's great! Take this prompt and hack it to make whatever works for you. Another quick note: I've customized the colors of my Terminal. They're based on the Monokai TextMate theme, and I think they look very nice. The colors will be different for you. If you want colors like mine you should take a look at the entry I wrote about it. Many people use the command line every day and never bother to customize their prompts.

It's just a bit of text that's printed before every command — why should you waste time learning how to customize it? I feel that the most important aspect of my command line work is the prompt. Your prompt is something you'll see literally thousands of times a day.

Why not take 30 minutes and customize it into something that's much more useful? I firmly believe I'm right in thinking this way. As I mentioned earlier I now use Zsh as my command line shell. If you use bash the default on most modern systems the syntax to create the shell will be different. I can write all day, but in the end I think a screenshot will be more helpful than anything I write.

The first thing I'd do when starting out with Zsh is to install robbyrussell's oh-my-zsh. It's a great collection of very useful Zsh configurations and aliases which set some sane defaults and make working with Zsh much nicer. An oh-my-zsh theme file is just a Zsh script which sets a few variables that the oh-my-zsh scripts use to render your prompt. Go ahead and create a new theme file for your prompt. Call it whatever you like. I called my theme "prose" because it's more verbose than the others.

Copy the contents of one of the other themes to get started. The first two pieces of my prompt are the simplest: username and hostname. I SSH between machines pretty frequently so I find it nice to have these in my prompt to remind me of where I am.

These are things that you'll find in many, many Zsh prompts. For more information about this kind of stuff check out this page.

Moving to zsh, part 6 – Customizing the zsh Prompt

I like to have the current working directory displayed in my prompt. Zsh has two built-in ways to show the current directory:. I work exclusively on laptops.Apple has announced that in macOS In this series, I will document my experiences moving bash settings, configurations, and scripts over to zsh.

This series has grown into a book : reworked and expanded with more detail and topics. Like my other books, I plan to update and add to it after release as well, keeping it relevant and useful. You can order it on the Apple Books Store now. Call me old-fashioned. In the snow!

Both ways! The default bash prompt on macOS is quite elaborate. It shows the username, the hostname, and the current directory. I have written before how I re-configured my bash prompt to have the information I want:. The basic zsh prompt configuration works similar to basheven though it uses a different syntax. The different placeholders are described in detail in the zsh manual.

The zsh default prompt is far shorter than the bash default, but even less useful. Since I work on the local system most of the time, the hostname bears no useful information, and repeating it every line is superfluous.

Note: you can argue that the hostname in the prompt is useful when you frequently have multiple terminal windows open to different hosts. This is true, but then the prompt is defined by the remote shell and its configuration files on the remote host.

There are more ways of showing the host in remote shell sessions, for example in the Terminal window title bar or with different window background colors. In our first iteration, I want to show the current working directory instead of the hostname. The first two do exactly the same.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

NOTE: In all likelihood, you will need to install a Powerline-patched font for this theme to render correctly. The result should look like this:. I don't want to clutter it up too much, but I am toying with the idea of adding RVM ruby version and n node.

It's currently hideously slow, especially inside a git repo. I guess it's not overly so for comparable themes, but it bugs me, and I'd love to hear ideas about how to improve the performance.

Would be nice for the code to be a bit more sane and re-usable. Also the dependency on a powerline-patched font is regrettable, but there's really no way to get that effect without it. Ideally there would be a way to check for compatibility, or maybe even fall back to one of the similar unicode glyphs. Skip to content.

See the graphic representation. Although Zsh is usable out of the box, it is almost certainly not set up the way most users would like to use it, but due to the sheer amount of customization available in Zsh, configuring Zsh can be a daunting and time-consuming experience. Included below is a sample configuration file, it provides a decent set of default options as well as giving examples of many ways that Zsh can be customized.

In order to use this configuration save it as a file named. Zsh ties the PATH variable to an path array. They are automatically synchronized. This allows us to easily manipulate PATH by simply modifying the array. Perhaps the most compelling feature of Zsh is its advanced autocompletion abilities. At the very least, enable autocompletion in. For enabling autocompletion of privileged environments in privileged commands e.

Read A closer look at the zsh line editor and creating custom widgets for an introduction to ZLE configuration. ZLE has an Emacs mode and a vi mode. Set the mode explicitly with bindkey -e or bindkey -v respectively for Emacs mode or vi mode. Key bindings are assigned by mapping an escape sequence matching a keypress to a ZLE widget. The available widgets, with descriptions of their actions and their default keybindings, are listed in zshzle 1 and zshcontrib 1.

The recommended way to set key bindings in Zsh is by using string capabilities from terminfo 5. For example [1] [2] :.

You need to set up the key array and make sure that ZLE enters application mode to use the following instructions; see Key bindings. By doing this, only the past commands matching the current line up to the current cursor position will be shown when Up or Down keys are pressed.
