What this tool does
Shell argument escaping wraps and escapes text so spaces and control characters are passed as literal argument content rather than shell syntax.
The tool quotes values differently for POSIX shells, PowerShell, and CMD while scanning for command-control characters.
Prefer APIs that pass argument arrays directly instead of building command strings from user input.
Example
Input: file name; rm -rf / → Output for Bash: 'file name; rm -rf /'
Use cases
- Escaping filenames in scripts
- Preparing curl arguments
- Protecting generated CLI commands
- Teaching command injection risks
Tips for better output
- Escape arguments, not complete trusted commands.
- Use argument-array APIs when available.
- Be extra careful with semicolons, pipes, backticks, and dollar signs.
- Choose the shell that will actually execute the command.
