Shell Syntax Converter is a lightweight developer tool for translating everyday terminal commands between CMD, PowerShell, and Bash/WSL.
It is built for the common moments where a command is familiar in one shell but awkward to remember in another. Instead of searching for the same equivalents repeatedly, users can paste a command, choose a source shell and target shell, and get a practical translation instantly.
What It Does
Shell Syntax Converter helps convert common command-line operations across three shell environments:
- CMD
- PowerShell
- Bash / WSL
It supports common workflows such as:
- Listing files
- Reading files
- Copying, moving, and deleting files
- Creating and removing directories
- Searching text
- Viewing processes
- Killing processes
- Checking network and IP information
- Running ping and DNS lookups
- Finding command help
- Converting basic web request commands
The app also includes a quick reference cheatsheet so users can browse common equivalents without typing a command first.
Why It Exists
Developers often move between Windows CMD, PowerShell, Linux shells, remote servers, containers, and WSL. The intent behind many commands is the same, but the syntax changes:
dir
Get-ChildItem
ls -la
Shell Syntax Converter focuses on those practical, repeated translations. It is not meant to replace shell documentation or parse every possible command. It is designed to cover useful command patterns quickly and clearly.
Key Features
Command Conversion
Type or paste a command, select the source shell, select the target shell, and the app converts the command when a matching rule exists.
Shell Switching
The source and target shells can be changed at any time. A swap control lets users quickly reverse the conversion direction.
Copy Shortcut
Converted output can be copied from the UI. Users can also press Ctrl+Enter or Cmd+Enter to copy the current output.
Quick Reference Cheatsheet
The cheatsheet lists common operations and their equivalents in CMD, PowerShell, and Bash. Clicking a cheatsheet item loads the command into the converter.
Filterable Commands
The cheatsheet can be filtered by operation name or command text, making it easier to find a specific command pattern.
Static, Fast, and Private
The app runs entirely in the browser. It does not send commands to a server or rely on an API for conversion.
Who It Is For
Shell Syntax Converter is useful for:
- Developers switching between Windows, Linux, and WSL
- Students learning shell differences
- PowerShell users translating from older CMD habits
- Windows users working with Bash examples
- Linux users reading Windows command examples
- Anyone who wants quick command syntax reminders
Technical Overview
The project is a static React application built with Vite and TypeScript.
The command data is stored as typed rule sets. Each conversion direction has its own rule group, such as:
- cmd_to_ps
- cmd_to_bash
- ps_to_cmd
- ps_to_bash
- bash_to_cmd
- bash_to_ps
When a user enters a command, the converter checks the relevant group and applies the first matching rule that changes the input.
This approach keeps the tool lightweight and easy to maintain while still covering many common shell translations.
Limitations
Shell Syntax Converter uses pattern-based conversion, not full shell parsing.
That means:
- Complex quoting may need manual adjustment.
- Shell-specific flags may not always have direct equivalents.
- Chained commands and scripts may require review.
- Some conversions are approximate because shells behave differently.
The output should be treated as a helpful starting point, especially for destructive commands.
