pub fn sanitize_command(
    command: &str,
    max_chars: Option<usize>,
) -> Result<String>

Sanitize a command before execution

This function:

• Validates that the command is not empty
• Trims whitespace
• Checks length against max_chars limit

Arguments

• command - The raw command string
• max_chars - Optional maximum character limit (None = unlimited)

Returns

• Ok(String) - The sanitized command
• Err(SshMcpError::InvalidParams) - If command is empty or too long

Examples

use ssh_mcp::ssh::sanitize::sanitize_command;

let cmd = sanitize_command("  ls -la  ", Some(1000)).unwrap();
assert_eq!(cmd, "ls -la");

// Too long command
let result = sanitize_command("a".repeat(100).as_str(), Some(50));
assert!(result.is_err());
