The secondary prompt (PS2) is used to prompt the user with whatever string they want to indicate a command continuation line. For example, if I use the standard PS2 prompt and type in the command:
cat abc def \
The shell will prompt me for the rest of the line with a ? mark or some other character. I usually set my secondary prompt for something more interesting, such as:
PS2='more ? '
So that I know that the shell wants more information before executing the command line.
The usual indication of running as the administrator in Unix is show a prompt that contains the '#' character as either the prompt or part of the prompt.
The prompt is an indication that the system is waiting for work to do, i.e. waiting for you type in a command.
Use the shell variable PS1 to set the command prompt to whatever you need.

Depends on what you mean by a "job". You can compile a program.
You really can't. There is nothing in a prompt that would give that information.
Use the following: PS1='$PWD : '
A Unix shell can be obtained in Cygwin, a Unix compatibility layer used to compile Unix programs and run them on Windows. Microsoft also makes a shell known as "Windows PowerShell" which incorporates more Unix-like features than the standard command prompt.
In Windows and Unix-based and Unix-like systems, the command is mkdir (however in Windows a shortcut md can be used as well).
You can log in via telnet or ssh protocol for a command line prompt environment to Unix, or you can use a graphical user interface such as KDE or Gnome, or the CDE environment via X-windows. In any of these protocols, you must supply a username and password to successfully log into the Unix system.
Most people set up their shell to give them an indication in the command prompt. But this isn't "built in" (the mechanism for doing so is built in to most shells, but you can use the same mechanism to change the prompt to pretty much anything you want).The command pwd on a Unix system should tell you "where you are".
It generally refers to setting the text that will appear when the shell prompt is asking the user to type in a command, meaning, the shell needs work to do. The standard prompt in most shell environments is a single character, such as '#', '$', or '%'. By setting the prompt you can customize what appears when the system is idle and wants you to type in a command to do something.
