Even though the UNIX system introduces a number of innovative programs and techniques, no single program or idea makes it work well. Instead, what makes it effective is the approach to programming, a philosophy of using the computer. Although that philosophy cant be written down in a single sentence, at its heart is the idea that the power of a system comes more from the relationships among programs than from the programs themselves. PTSource Shell is a free UNIX programming environment compatible environment for Windows x86 and x64 included in the PTSource Developer Platform. Its goal is to allow programs of UNIX like systems to be recompiled and run natively on Windows with minimal source code modifications by providing them with the same underlying API they would expect in those systems. PTSource Shell provides native integration of Windows based applications, data, and other system resources with applications, software tools, and data of the UNIX like environment. Thus it is possible to launch Windows applications from the PTSource Shell environment, as well as to use PTSource Shell tools and applications within the Windows operating context.

A non-quoted backslash \ is the Bash escape character. It preserves the literal value of the next character that follows, with the exception of newline. If a \newline pair appears, and the backslash itself is not quoted, the \newline is treated as a line continuation (that is, it is removed from the input stream and effectively ignored). So moving in dirs in the Shell its slightly different so if you want to walk thru dirs you shoud use / instead of \ as in *nix.

cd c:\   
# This is wrong and it will return c:
cd c:/   
# This is right and it will return c:\
cd c:\\
# This is also right and it will return c:\

PTSource Shell uses a simple ini file called PTShell.ini in the PTSource directory as its RC startup it fully supports aliases and it reads by default as fallows :
