When comparing zsh vs IntelliJ IDEA, the Slant community recommends IntelliJ IDEA for most people. In the question“What are the best power user tools for macOS?” IntelliJ IDEA is ranked 39th while zsh is ranked 47th. The most important reason people chose IntelliJ IDEA is:
IDEA places an emphasis in safe refactoring, offering a [variety of features](https://www.jetbrains.com/idea/features/refactoring.html) to make this possible for a variety of languages. These features include safe delete, type migration and replacing method code duplicates.
Ranked in these QuestionsQuestion Ranking
Pro Interactive autocompletion
When you start typing a command, you can press the tab key and it will complete the command you started typing. If there are multiple potential commands, you can choose which one to run by simply pressing tab again. Case-insensitive by default, too.
Pro Powerful community-driven tools via oh-my-zsh
Oh-my-zsh is a community-driven framework, which helps users with their zsh configuration and plugins. 400 plugins, 200+ themes and auto-updates to always be up to date.
Pro Autocomplete for options
Zsh intelligently determines if you are trying to complete a file path or an option, and pressing tab after typing
- will reliably bring up a list of options.
Pro Good bash compatibility
Things you've learned using bash will largely apply to zsh. Scripts written in bash will run with little to no modification.
Pro Shared histories
If you spend a lot of time in the terminal, most likely you will have several terminal windows open. Zsh has great support for command line histories. The history is unique and shared through all the different instances.
Pro Smart escaping
Zsh can determine the context of the command you're typing in and determine if it should escape characters if you're typing in a URI.
Pro Recursive globbing
ls **/*.log for example is supported by ZSH.
Pro Pipe output to a temporary file:
Some programs don't support loading from stdin, but ZSH can store outputs to a temporary file, example:
unzip =(curl http://example.com/someZipFile.zip)
Pro Great install procedure
Zsh will take you through a procedure which is roughly 30 minutes in length before during install. Through this procedure it asks you to set different options and customize the shell the way you want it to. Most of these settings are also found in other shells, but to customize them you have to go dig configuration files while zsh allows you to do it in the beginning.
Pro Faster spelling correction
Zsh' s correct (or correctall) is vastly superior to Bash's attempt at spelling correction.
Pro Smart refactorings
IDEA places an emphasis in safe refactoring, offering a variety of features to make this possible for a variety of languages.
These features include safe delete, type migration and replacing method code duplicates.
Pro Fast and smart contextual assistance
Uses a fast indexing technique to provide contextual hints (auto-completion, available object members, import suggestions).
On-the-fly code analysis to detect errors and propose refactorization.
Pro Android support, JavaEE support, etc
A very complete development environment support.
Pro Stable and robust
IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.
Pro Support for many languages
IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc.
Pro Intuitive and slick UI
IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).
Pro Lots of plugins
Many plugins are available for almost any task a developer may need to cover. Plugins are developed by Jetbrains themselves or by 3rd parties through the SDK available for writing them.
Pro Clear and detailed documentation
The documentation is exhaustive, easy to navigate, and clearly worded.
Pro Free version available
There is a free community edition (open source) and an ultimate edition, which you can compare here.
The ultimate edition is available for free for one year for students but must be registered through an .edu e-mail account.
Pro Many convenient features
These simplify the daily work, e.g. copy/cut a whole line without the need to select it.
Pro Very powerful debugger
With ability to step into a certain part of a large method invocation (Shift+F7), drop frame, executing code snippets, showing method return values, etc.
Pro Buit-in Git support
Pro Gradle support
Con Defaults are unfriendly for a long-time bash user
Expect to find a configuration you like (or use the configuration utility) to set reasonable preferences. Default zsh interaction is different enough to make you stutter through what used to be familiar workflows.
Con Requires a lot of configuration to be used fully
Zsh requires a lot of tinkering with configuration files and downloading plugins in order to be able to do tasks which other shells may be able to do out of the box.
Con Not fully compatible with bash
There is a small chance you may have a bash script that doesn't work in zsh, although this is very very rare and most developers will never run into any issues.
Con Slow startup
Startup can be slow deepending on system configuration
Con Uses too much RAM
Con Standard hotkeys behave differently
Seems like hotkeys assignment in Idea has no logical consistency.
Like «F3» is usually next match, «Ctrl+W» - close tab, etc — they map to some different action by default.
There is a good effort in making the IDE friendly for immigrants from other products: there are options to use hotkeys from Eclipse, and even emacs. But these mappings are very incomplete. And help pages do not take this remapping into account, rather mentioning the standard hotkeys.
So, people coming from other IDEs/editors are doomed to using mouse and context menus (which are rather big and complex).
Con Bugs are not solved as often as they should
They are more interested in adding new features or issuing new versions than solving bugs.
Con Cannot open multiple projects in the same window
Con Built with closed source components
The version with full features is not opensource. Parts of the code are under apache licence though.
Con Lack of plugins
IntelliJ supports a very small amount of plugins. Although these are 'quality approved', many features are missing and can't be implemented because of that.
