child process

The code utilizes the child_process and importer modules to execute external Bash commands and handle errors, with functions such as bashToExec and execCmd to prepare and run the commands. The execCmd function creates a promise that resolves with the output of the executed command and logs the command and its output if not in quiet mode.

The code combines asynchronous operations with error handling in Node.js, initiating a test suite, executing a shell command, and handling the result or error through custom functions.

However, for brevity I could remove the Node.js and shell command execution to just convey that it's asynchronous and has error-handling in one sentence.

The code is asynchronous, with error handling and uses a test suite.

The bashToOne function maps Bash shell script code to a single executable command, handling platform-specific line endings and command separators. It does this by splitting, modifying, and joining the input code according to the detected platform (Windows or Unix-like).
