direct.h is a C/C++ header file provided by Microsoft Windows, which contains functions for manipulating file system directories. Some POSIX functions that do similar things are in unistd.h . Member functions
Node.js programs are invoked by running the interpreter node interpreter with a given file, so the first two arguments will be node and the name of the JavaScript source file. It is often useful to extract the rest of the arguments by slicing a sub-array from process.argv .
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.
Command-line arguments are passed in args. As in C and C++, the name "main()" is special. Java's main methods do not return a value directly, but one can be passed by using the System.exit() method. Unlike C, the name of the program is not included in args, because it is the name of the class that contains the main method, so it is already ...
A command-line argument or parameter is an item of information provided to a program when it is started. [23] A program can have many command-line arguments that identify sources or destinations of information, or that alter the operation of the program. When a command processor is active a program is typically invoked by typing its name ...
The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. 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 cmd.exe command processor of Windows NT-based systems supports basic completion. It is possible to use a separate key-binding for matching directory names only. cmd.exe /F:ON enables file and directory name completion characters (^F and ^D by default).
where name_of_directory is the name of the directory one wants to create. When typed as above (i.e. normal usage), the new directory would be created within the current directory. On Unix and Windows (with Command extensions enabled, [15] the default [16]), multiple directories can be specified, and mkdir will try to create all of them.
