75 Zsh Commands, Plugins, Aliases and Tools

Zsh: 75 commands, plugins, alias and tools to help you improve terminal efficiency

I work most of my time every day at the terminal, and the shell I chose is Zsh – a highly customizable Unix shell with many powerful features. As a lazy developer™, I've been looking for ways to reduce the amount of input and automate all tasks. Fortunately, Zsh was born for this.

In this article, I will share 75 commands, plugins, alias and tools, hoping to help you save some key presses and improve your daily work efficiency.

If you haven't installed Zsh on your machine, check out this article and I'll show you how to get started quickly.

Key Points

• Zsh is a highly customizable Unix shell that is ideal for developers looking to automate tasks and increase productivity by reducing the number of key presses.
• This article provides a comprehensive guide to 75 Zsh commands, plugins, alias, and tools, including practical applications and customization tips.
• Zsh's key features include powerful command-line navigation, conditional execution, and the ability to efficiently link multiple commands.
• Oh My Zsh, a community-driven framework that simplifies your workflow by providing thousands of useful functions, plugins, and themes.
• This article also highlights the use of aliases and plugins that can significantly speed up common tasks and simplify complex commands in Zsh.

Zsh's 15 out-of-the-box features

Zsh shares many convenient features with Bash. The following features are not unique to Zsh, but are still worth knowing. I encourage you to start using the command line to do the actions listed below. At first it may seem like it's more laborious than using a GUI, but once you get the trick, you'll never regret it.

• Enter cd from anywhere in the file system will take you back to your home directory directly.
• Enter !! will call up the last command. This will be very convenient if the command fails because administrator privileges are required. In this case, you can enter sudo !!.
• You can use && to link multiple commands. For example, mkdir project && cd project && npm init -y.
• Use || to perform conditional execution. For example, git commit -m "whatever..." || echo "Commit failed".
• Using the mkdir command's -p switch will allow you to create a parent directory as needed. Use curly braces to expand to reduce duplication. For example, mkdir -p articles/jim/sitepoint/article{1,2,3}.
• Set environment variables based on each command, for example: NODE_DEBUG=myapp node index.js. Or, set on a per-session basis: export NODE_DEBUG=myapp. You can check if it is set by typing echo $variable-name.
• Transfer the output of one command to the second command. For example, cat /var/log/kern.log | less makes long logs easy to read, or history | grep ssh searches for any history entry containing "ssh".
• You can open files from the terminal in your editor. For example, nano ~/.zshrc (nano), subl ~/.zshrc (Sublime Text), code ~/.zshrc (VS Code). If the file does not exist, it will be created when you press "Save" in the editor.
• Navigation is an important skill. Don't rely on your arrow keys just. For example, <kbd>Ctrl</kbd> <kbd>a</kbd> will take you to the beginning of a line.
• And <kbd>Ctrl</kbd> <kbd>e</kbd> will take you to the end.
• You can use <kbd>Ctrl</kbd> <kbd>w</kbd> to delete a word (backward).
• <kbd>Ctrl</kbd> <kbd>u</kbd> will delete everything from the cursor to the beginning of the line.
• <kbd>Ctrl</kbd> <kbd>k</kbd> Clears everything from the cursor to the end of the line. The last three can be undoed using <kbd>Ctrl</kbd> <kbd>y</kbd>.
• You can use <kbd>Ctrl</kbd> <kbd>Shift</kbd> <kbd>c</kbd> to copy text. This is much more elegant than right-clicking and selecting Copy.
• Instead, you can use <kbd>Ctrl</kbd> <kbd>shift</kbd> <kbd>v</kbd> to paste copied text.

Try to remember these key combinations. You'll be surprised at how often they come in handy.

15 custom aliases to increase your productivity

Alias ​​is a terminal shortcut for regular commands. You can add them to your ~/.zshrc file and reload your terminal (using source ~/.zshrc) to make them take effect.

The syntax for declaring (simple) alias is as follows:

<code>alias [alias-name]='[command]'</code>

Alias ​​is perfect for common commands, long commands, or commands that are difficult to remember in syntax. Here are some aliases that I often use:

• A myip alias that prints your current public IP address to the terminal: alias myip='curl http://ipecho.net/plain; echo'.

• A distro a alias distro='cat /etc/*-release' alias that outputs information about your Linux distribution:

  .

• reloadA alias reload='source ~/.zshrc' a

  alias, because I always can't seem to remember how to reload my terminal:
.

• undo-git-reset alias undo-git-reset-head="git reset 'HEAD@{1}'"A git reset HEAD~Alias:

  . This will restore the effect of running
.

• alias sapu='sudo apt-get update'

  A alias for an update package list:
.

• alias ffs='sudo !!'

  A alias that reruns the previous command using sudo:
.

• y yarnBecause I'm lazy, I'll use alias y='yarn' as an alias for the <kbd>y</kbd> command:

  . This means I can clone a repository and then just type
to introduce all the dependencies. I learned this from Scott Tolinski on Syntax.

• node_modules package-lock.jsonI don't use it often, but this alias clears the alias yolo='rm -rf node_modules/ && rm package-lock.json && yarn install' folder and deletes the file, and then reinstalls the project's dependencies: . As you may know, yolo stands for You Only Live

  O
nce.

• .zshrc alias zshconfig='subl $HOME/.zshrc'A alias that opens my

  file for editing:
.

• alias update-available-rubies='cd ~/.rbenv/plugins/ruby-build && git pull'

  A alias for an updated list of Ruby versions that rbenv can install:

• alias server='python -m SimpleHTTPServer 8000'

  A alias to start the server in your current directory (no npm package required):
.

• alias npmhelp='firefox https://github.com/robbyrussell/oh-my-zsh/tree/master/plugins/npm'

  You can also create an alias to open the document in your browser:
.

• alias -g L='| less' cat production.log LA global alias for pipes the output of the command to less:

  . You can use it like this:
.

• alias -g G='| grep' history G sshA global alias for pipes the output of the command to grep:

  . You can use it like this:
.

• You can also use functions to create alias. The following (taken from here) creates an alias to add, commit and push code to GitHub:

  <code>alias [alias-name]='[command]'</code>

There are many places to find more ideas about alias online. For example, this Hacker News discussion, or this article about using Zsh to improve command line productivity.

15 cool things you can do with (Oh My) Zsh

Oh My Zsh is a community-driven framework for managing your Zsh configuration and bundled with thousands of useful functions, assistants, plugins, and themes. If you are going to use the Z shell as your daily driver, you should really install Oh My Zsh.

The
• take command will create a new directory and enter the directory. take my-project Replace mkdir my-project && cd my-project.
• zsh_stats will provide you with a list of the first 20 commands and their number of runs.
• Oh My Zsh simplifies your file system navigation. For example, .. is an alias for cd ....
• Similarly, ... moves you upwards two directories, .... moves three upwards, and ..... moves four upwards.
• You can omit cd when navigating. For example, entering / will take you directly to your file system root directory.
• also supports partial matching. For example, enter /h/j/De and press <kbd>TAB</kbd> and then <kbd>Return</kbd> will take me to /home/jim/Desktop/.
• rd is an alias for rmdir and md is an alias for mkdir -p.
• You can enter d to list the last directory used in the terminal session.
• You can then use cd -n to navigate to any of these directories, where n is the directory number.
• Tab completion is another great feature. For example, entering ls - and pressing <kbd>TAB</kbd> will list all command options, as well as a useful description of their functions. This also applies to cap, rake, ssh and kill.
• Enter alias All your current aliases will be listed.
• Using wildcards (Zsh function), you can list files with specific extensions. For example, ls *.html will list all HTML files in the current directory. To include subdirectories, change to: ls **/*.html.
• Wildcard qualifier allows you to use flags to select file types. For example, ls -l **/*(.x) will find all executables in the current directory and all subdirectories.

Other Resources

The main job of the plug-in listed above is to provide alias for common commands. Note that there are many other plugins that can add additional features to your shell.

The following are four of my favorites:

• sudo allows you to easily prefix the current or previous command by pressing <kbd>ESC</kbd> twice. sudo
• Suggest commands as you type based on history and complete content. If the suggestion is the command you are looking for, press the autosuggestions key to accept it. A real time-saving tool! <kbd>→</kbd>
• : If the command is not recognized in command-not-found, it will use the Ubuntu's $PATH package to find it or suggest a misspelling. command-not-found
• is a handy plugin that builds your most commonly used and recent folder lists (it is called "frecent") and allows you to jump to them with a command. z

Don't forget that if you spend a lot of time on the terminal, it's worth it to make it more visually appealing. Fortunately, Oh My Zsh comes with a lot of themes for you to choose from. My favorite topic is Agnoster.

How to use Zsh arrays?

Zsh supports indexed arrays and associative arrays. You can use the set command followed by the array name and element to create an index array. For example, to create a color array, you can use: set -A colors red green blue. You can access elements of an array using its index: echo $colors[1]. To create an associative array, you can use the typeset command: typeset -A colors; colors[red]=#FF0000; colors[green]=#00FF00; colors[blue]=#0000FF;.

How to use Zsh loop?

Zsh supports several types of loops, including for, while, and until loops. The for loop allows you to execute command blocks repeatedly for each element in the list. For example, to print numbers from 1 to 5, you can use: for i in {1..5}; do echo $i; done. The while loop allows you to repeat the command block when the condition is true. For example, to print numbers from 1 to 5, you can use: i=1; while (( i < 6 )); do echo $i; i=$((i 1)); done. The until loop allows you to repeat the command block when the condition is false. For example, to print numbers from 1 to 5, you can use: i=1; until (( i > 5 )); do echo $i; i=$((i 1)); done.
