If you're an active Mac user that spends a good amount of time using shell, you may have noticed that the OSX Shell by default is bear bone and not very productive to use on a daily bases.

The question is, how we can make OSX shell more productive?

Getting Started

Install/Deploy iTerm2

iTerm2 is a replacement for Terminal and the successor to iTerm that brings multiple new features and optimizations that can make users more efficient.

We can iTerm2 download from the official Web Site.

iTerm2 provides features, including Split Panes, Search, Autocomplete, Split Panes, Instant Replay, etc. You can read more on their official Documentation Page.

You may also like: Implement a Command-Line Shell by Using Command Dispatcher in Python.

Install Xcode

Just running below command in the iTer2 will install Xcode.

Deploy Homebrew

Homebrew is the most used package manager for Apple macOS

Installation is a straight forward process. Simply run the following command in iTerm2.

Once we have Homebrew installed, we can update it.

OSX by default comes with Python 2.7 installed, so we're going to update to the latest version of Python using brew. Then, we're going to deploy the newest version of git and vim and install neovim as a potential replacement for vim. In addition, we will install a few more useful packages that come into the light later

As for Python, we can use pip to install to add any other packages/modules we may need.

Now, let's make our shell shine.

Add the following lines to your ~/.bash_profile that will execute ~/.bashrc during the terminal launch.

We can now make our bash prompt more colorful and useful by adding bash_completion. In the ~/.bashrc file, add the following code.

Now, we can configure the rest of bash (e.g. history aliases some color for man pages and nice color output for less and cat commands).

Add below lines to your ~/.bashrc file

Example for ~/.vimrc:

Let's enhance our command history; instead of cycling with up and down arrow keys through the entire history of the commands, you can type a command and cycle only for the latest history of the SYNOPSIS Ex. ls-a, ls -la, ls -la / ls -la /etc. Once you type ls, you can navigate through past commands you used.

Create a file in the home directory .inputrc and add the following entries

Add below entry to ~/.bashrc to import settings from ~/.inputrc.

If you are a git user and use git CLI from the shell, it is nice to know what branch you are in without typing git branch.

Download both files from following links into your home directory ~/.

Then add the following lines into ~/.bashrc.

Another useful tool to keep in mind is tmux.

Tmux is a terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command line program at the same time. It can also be used to detach processes from their controlling terminals, allowing SSH sessions to remain active without being visible.

Install tmux.

Below is the configuration file used to configure tmux~/.tmux.conf.

We change activition key binding for tmux from default Ctrl+b to Ctrl+a similar to screen.

Now that we configure nice-looking bash shell and terminal and learn how to take advantage of the added options we can move to a more advanced terminal and maybe even try to replace bash with more modern-looking shell FISH.

FISH, the friendly interactive shell, is a Unix shell that attempts to be more interactive and user-friendly.

Let's start by installing the FISH shell and a few add-ons like theme manager, oh-my-fish, that can male our FISH fly.

In the above example, we install FISH and oh-my-fish and deployed 'bobthefish' as a theme.

To make the FISH look even better, let's install powerline and fonts.

To make the FISH shell default when you start terminal usechshwhere you can replace bash with theFISH path

Do not forget to change fonts for iTerm2 to add newly installed fonts.

In Preferences../Profile/Text

You can add an additional configuration option for oh my FISH by editing and adding below lines to ~/.config/fish/config.fish.

For tmux to start with FISH, you can add below two lines to the beginning of the ~/.tmux.conf.

To add aliases you can add to ~/.config/fish/functions/.

Examples you can find at https://github.com/mudrii/.files/tree/master/HWD_Mac/.config/fish/functions.

Your terminal should look much better with FISH and tmux.

We are not done yet; let's make vim look nice with our shell theme and functionality.

The first step is to install vim-plug, as the vim plugin manager, where can manage, install, and uninstall all needed plugins for vim.

Edit your ~/.vimrc config file for vim and add the following lines.

Open vim and run PlugInstall. This will install all plugins defined in ~/.vimrc.

The rest of ~/.vimrc (with some neat configuration options) can be found here.

With a few more useful apps, you can make use of are ranger as a file-manager in the shell terminal, bat as a replacement for cat, htop console process viewer manager, fdas areplacement for find, and p7zp advance archiver.

All configuration files used in this article you can find here.

Welcome to Docker Desktop! The Docker Desktop for Mac user manual provides information on how to configure and manage your Docker Desktop settings.

For information about Docker Desktop download, system requirements, and installation instructions, see Install Docker Desktop.

Preferences

The Docker Preferences menu allows you to configure your Docker settings such as installation, updates, version channels, Docker Hub login,and more.

Choose the Docker menu > Preferences from themenu bar and configure the runtime options described below.

General

On the General tab, you can configure when to start and update Docker:

• Automatically check for updates: By default, Docker Desktop is configured to check for newer versions automatically. If you have installed Docker Desktop as part of an organization, you may not be able to update Docker Desktop yourself. In that case, upgrade your existing organization to a Team plan and clear this checkbox to disable the automatic check for updates.

• Start Docker Desktop when you log in: Automatically starts Docker Desktop when you open your session.

• Include VM in Time Machine backups: Select this option to back up the Docker Desktop virtual machine. This option is disabled by default.

• Use gRPC FUSE for file sharing: Clear this checkbox to use the legacy osxfs file sharing instead.

• Send usage statistics: Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out.

• Show weekly tips: Displays useful advice and suggestions about using Docker.

• Open Docker Desktop dashboard at startup: Automatically opens the dashboard when starting Docker Desktop.

Resources

The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources.

Advanced

On the Advanced tab, you can limit resources available to Docker.

Fish (nicmagnier) Mac Os Update

Advanced settings are:

• CPUs: By default, Docker Desktop is set to use half the number of processorsavailable on the host machine. To increase processing power, set this to ahigher number; to decrease, lower the number.

• Memory: By default, Docker Desktop is set to use 2 GB runtime memory,allocated from the total available memory on your Mac. To increase the RAM, set this to a higher number. To decrease it, lower the number.

• Swap: Configure swap file size as needed. The default is 1 GB.

• Disk image size: Specify the size of the disk image.

• Disk image location: Specify the location of the Linux volume where containers and images are stored.

You can also move the disk image to a different location. If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it.

File sharing

Use File sharing to allow local directories on the Mac to be shared with Linux containers.This is especially useful forediting source code in an IDE on the host while running and testing the code in a container.By default the /Users, /Volume, /private, /tmp and /var/folders directory are shared. If your project is outside this directory then it must be addedto the list. Otherwise you may get Mounts denied or cannot start service errors at runtime.

File share settings are:

• Add a Directory: Click + and navigate to the directory you want to add.

• Apply & Restart makes the directory available to containers using Docker’sbind mount (-v) feature.

Tips on shared folders, permissions, and volume mounts

• Share only the directories that you need with the container. File sharing introduces overhead as any changes to the files on the host need to be notified to the Linux VM. Sharing too many files can lead to high CPU load and slow filesystem performance.

• Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume (named volume) or data container.

• If you share the whole of your home directory into a container, MacOS may prompt you to give Docker access to personal areas of your home directory such as your Reminders or Downloads.

• By default, Mac file systems are case-insensitive while Linux is case-sensitive. On Linux, it is possible to create 2 separate files: test and Test, while on Mac these filenames would actually refer to the same underlying file. This can lead to problems where an app works correctly on a Mac (where the file contents are shared) but fails when run in Linux in production (where the file contents are distinct). To avoid this, Docker Desktop insists that all shared files are accessed as their original case. Therefore, if a file is created called test, it must be opened as test. Attempts to open Test will fail with the error No such file or directory. Similarly, once a file called test is created, attempts to create a second file called Test will fail. For more information, see Volume mounting requires file sharing for any project directories outside of /Users.)

Proxies

Docker Desktop detects HTTP/HTTPS Proxy Settings from macOS and automaticallypropagates these to Docker. For example, if you set yourproxy settings to http://proxy.example.com, Docker uses this proxy whenpulling containers.

Your proxy settings, however, will not be propagated into the containers you start.If you wish to set the proxy settings for your containers, you need to defineenvironment variables for them, just like you would do on Linux, for example:

For more information on setting environment variables for running containers,see Set environment variables.

Network

You can configure Docker Desktop networking to work on a virtual private network (VPN). Specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity.

Docker Engine

The Docker Engine page allows you to configure the Docker daemon to determine how your containers run.

Type a JSON configuration file in the box to configure the daemon settings. For a full list of options, see the Docker Enginedockerd commandline reference.

Click Apply & Restart to save your settings and restart Docker Desktop.

Command Line

On the Command Line page, you can specify whether or not to enable experimental features.

Experimental features provide early access to future product functionality.These features are intended for testing and feedback only as they may changebetween releases without warning or can be removed entirely from a futurerelease. Experimental features must not be used in production environments.Docker does not offer support for experimental features.

For a list of current experimental features in the Docker CLI, see Docker CLI Experimental features.

You can toggle the experimental features on and off in Docker Desktop. If you toggle the experimental features off, Docker Desktop uses the current generally available release of Docker Engine.

You can see whether you are running experimental mode at the command line. IfExperimental is true, then Docker is running in experimental mode, as shownhere. (If false, Experimental mode is off.)

Kubernetes

Docker Desktop includes a standalone Kubernetes server that runs on your Mac, sothat you can test deploying your Docker workloads on Kubernetes. To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes.

For more information about using the Kubernetes integration with Docker Desktop, see Deploy on Kubernetes.

Reset

Reset and Restart options

On Docker Desktop Mac, the Restart Docker Desktop, Reset to factory defaults, and other reset options are available from the Troubleshoot menu.

For information about the reset options, see Logs and Troubleshooting.

Dashboard

The Docker Desktop Dashboard enables you to interact with containers and applications and manage the lifecycle of your applications directly from your machine. The Dashboard UI shows all running, stopped, and started containers with their state. It provides an intuitive interface to perform common actions to inspect and manage containers and existing Docker Compose applications. For more information, see Docker Desktop Dashboard.

Add TLS certificates

You can add trusted Certificate Authorities (CAs) (used to verify registryserver certificates) and client certificates (used to authenticate toregistries) to your Docker daemon.

Add custom CA certificates (server side)

All trusted CAs (root or intermediate) are supported. Docker Desktop creates acertificate bundle of all user-trusted CAs based on the Mac Keychain, andappends it to Moby trusted certificates. So if an enterprise SSL certificate istrusted by the user on the host, it is trusted by Docker Desktop.

To manually add a custom, self-signed certificate, start by adding thecertificate to the macOS keychain, which is picked up by Docker Desktop. Here isan example:

Or, if you prefer to add the certificate to your own local keychain only (ratherthan for all users), run this command instead:

See also, Directory structures forcertificates.

Note: You need to restart Docker Desktop after making any changes to thekeychain or to the ~/.docker/certs.d directory in order for the changes totake effect.

For a complete explanation of how to do this, see the blog post AddingSelf-signed Registry Certs to Docker & Docker Desktop forMac.

Add client certificates

Fish (nicmagnier) Mac Os X

You can put your client certificates in~/.docker/certs.d/<MyRegistry>:<Port>/client.cert and~/.docker/certs.d/<MyRegistry>:<Port>/client.key.

When the Docker Desktop application starts, it copies the ~/.docker/certs.dfolder on your Mac to the /etc/docker/certs.d directory on Moby (the DockerDesktop xhyve virtual machine).

• You need to restart Docker Desktop after making any changes to the keychainor to the ~/.docker/certs.d directory in order for the changes to takeeffect.

• The registry cannot be listed as an insecure registry (see DockerEngine. Docker Desktop ignores certificates listedunder insecure registries, and does not send client certificates. Commandslike docker run that attempt to pull from the registry produce errormessages on the command line, as well as on the registry.

Directory structures for certificates

If you have this directory structure, you do not need to manually add the CAcertificate to your Mac OS system login:

The following further illustrates and explains a configuration with customcertificates:

You can also have this directory structure, as long as the CA certificate isalso in your keychain.

To learn more about how to install a CA root certificate for the registry andhow to set the client TLS certificate for verification, seeVerify repository client with certificatesin the Docker Engine topics.

Install shell completion

Docker Desktop comes with scripts to enable completion for the docker and docker-compose commands. The completion scripts may befound inside Docker.app, in the Contents/Resources/etc/ directory and can beinstalled both in Bash and Zsh.

Bash

Bash has built-in support forcompletion To activate completion for Docker commands, these files need to becopied or symlinked to your bash_completion.d/ directory. For example, if youinstalled bash via Homebrew:

Add the following to your ~/.bash_profile:

OR

Zsh

In Zsh, the completionsystemtakes care of things. To activate completion for Docker commands,these files need to be copied or symlinked to your Zsh site-functions/directory. For example, if you installed Zsh via Homebrew:

Fish-Shell

Fish-shell also supports tab completion completionsystem. To activate completion for Docker commands,these files need to be copied or symlinked to your Fish-shell completions/directory.

Create the completions directory:

Now add fish completions from docker.
