py2exe is a Python extension which converts Python scripts (.py) into Microsoft Windows executables (.exe). These executables can run on a system without Python installed. [3] It is the most common tool for doing so.
Several open-source scripts have been developed to facilitate the construction of Python one-liners. Scripts such as pyp or Pyline import commonly used modules and provide more human-readable variables in an attempt to make Python functionality more accessible on the command line. Here is a redo of the above example (printing the last field of ...
Commands with long or difficult to spell filenames can be entered by typing the first few characters and pressing a completion key, which completes the command or filename. In the case of multiple possible completions, some command-line interpreters, especially Unix shells, will list all possible completions beginning with those few characters.
COMMAND.COM, the original Microsoft command line processor introduced on MS-DOS as well as Windows 9x, in 32-bit versions of NT-based Windows via NTVDM; cmd.exe, successor of COMMAND.COM introduced on OS/2 and Windows NT systems, although COMMAND.COM is still available in virtual DOS machines on IA-32 versions of those operating systems also.
Executable code, an executable file, or an executable program, sometimes simply referred to as an executable or binary, is a list of instructions and data to cause a computer "to perform indicated tasks according to encoded instructions", [1] as opposed to a data file that must be interpreted by a program to be meaningful.
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
It is the standard format for executables on Windows NT-based systems, including files such as .exe, .dll, .sys (for system drivers), and .mui. At its core, the PE format is a structured data container that gives the Windows operating system loader everything it needs to properly manage the executable code it contains.
Microsoft Windows [10] ReactOS [11] HP MPE/iX [12] KolibriOS [13] SymbOS; Unix and Unix-like operating systems; Many shells, including all Bourne-like (such as Bash [14] or zsh [15]) and Csh-like shells as well as COMMAND.COM and cmd.exe implement echo as a builtin command. The command is also available in the EFI shell. [16]
