PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located. In general, each executing process or user session has its own PATH setting.
A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure.It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory.
In most Unix and Unix-like command-line shells, an environment variable's value is retrieved by placing a $ sign before the variable's name. If necessary, the name can also be surrounded by braces. If necessary, the name can also be surrounded by braces.
In most computer file systems, every directory has an entry (usually named ".") which points to the directory itself.In most DOS and UNIX command shells, as well as in the Microsoft Windows command line interpreters cmd.exe and Windows PowerShell, the working directory can be changed by using the CD or CHDIR commands.
A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD systems use /home/ username or /usr/home/ username and Windows systems since Windows Vista use \Users\ username .
The directories in the path variable are searched in the order they are given. By re-ordering the path, one can run e.g. \OS2\MDOS\E.EXE instead of \OS2\E.EXE, when the default is the opposite. Renaming of the executables also works: people often rename their favourite editor to EDIT, for example.
If pushd is not provided with a path argument, in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories. The popd command removes (or 'pops', in the stack analogy) the current path entry from the stack and returns to the path at the top of the stack as the new working directory. [4] [5]
-classpath D:\myprogram sets the path to the packages used in the program (on Linux, -cp /home/user/myprogram) and org.mypackage.HelloWorld is the name of the main class Setting the path through an environment variable
