Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

private static string ParseIntWithTryParse()
{
    string result = string.Empty;
    if (int.TryParse(result, out var value))
        result = value.ToString();
    else
        result = "There is no int value";
    return $"Final result: {result}";
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

private static string ParseIntWithException()
{
    string result = string.Empty;
    try
    {
        result = Convert.ToInt32(result).ToString();
    }
    catch (Exception)
    {
        result = "There is no int value";
    }
    return $"Final result: {result}";

Any command-line input or output is written as follows:

sudo cp sample.service /lib/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable sample

Bold: Indicates a new term, an important word, or words that you see on the screen. For instance, words in menus or dialog boxes appear in the text like this. For example: “Select System info from the Administration panel.”
