Function label 

pub fn label(command: &str) -> String

Derive a short label from a command string.

Extracts the binary name, skipping any leading sudo/env prefix and stripping any path prefix. For example:

• “cargo test” → “cargo”
• “/usr/bin/python script.py” → “python”
• “gh issue list” → “gh”
• “sudo cargo test” → “cargo”
• “env FOO=bar cargo test” → “cargo”

If stripping the prefix leaves no token, the original first token is returned (e.g., “sudo” → “sudo”, “env” → “env”).

Arguments

• command - The command string

Returns

A short label derived from the command.
