Shell/Bash Online Compiler

Run Shell and Bash-style commands online in VulnTech's browser-side compiler with clean terminal output and controlled execution.

Run Shell/Bash Online in Your Browser

Use the Shell/Bash runner to practice basic command-line workflows like pwd, ls, cat, grep, wc, and sort. It is a browser-side virtual shell for learning, not access to a real server terminal.

Supported Languages

Shell/Bash support focuses on practical learning examples:

• pwd
• ls
• cat
• grep
• wc
• sort
• small shell scripts

Browser-Side Execution

Code execution stays browser-side through Web Workers and WebAssembly runtimes where needed. Runtimes are lazy-loaded only when the selected language needs them, and the server-side execution endpoint remains disabled.

Features

• Runs in a browser virtual shell
• terminal-style output
• safe practice files
• Stop and timeout controls

Practice Ideas

• Practice pwd, ls, cat, grep, wc, and sort against safe sample files.
• Combine basic commands to inspect text output.
• Learn command-line habits without access to a real server shell.

Example Exercises

Limitations

• Shell support is experimental
• It is not a real Linux server shell
• Networking, package managers, and OS-level access are not available
