PowerShell scripts (files suffixed by .ps1) PowerShell functions; Standalone executable programs; If a command is a standalone executable program, PowerShell launches it in a separate process; if it is a cmdlet, it executes in the PowerShell process. PowerShell provides an interactive command-line interface, where the commands can be
The Multics shell includes a run command to run a command in an isolated environment. [1] The DEC TOPS-10 [2] and TOPS-20 [3] Command Processor included a RUN command for running executable programs. In the BASIC programming language, RUN is used to start program execution from direct mode, or to start an overlay program from a loader program.
The command definition language supports many types of options, for example dates and file specifications, and allows a qualifier to change the image invoked—for example "CREATE", to create a file, vs. "CREATE/DIRECTORY" to create a directory. The other (simpler, but less flexible) method to define commands is via foreign commands. This is ...
For example, to undo a delete selection command, the object may contain a copy of the deleted text so that it can be re-inserted, if the delete selection command must be undone. Note that using a separate object for each invocation of a command is also an example of the chain of responsibility pattern. The term execute is also ambiguous.
In PowerShell, all types of commands (cmdlets, functions, script files) inherently expose data about the names, types and valid value ranges/lists for each argument. This metadata is used by PowerShell to automatically support argument name and value completion for built-in commands/functions, user-defined commands/functions as well as for ...
In this case, the "commands" are simply program instructions, whose execution is chained together. The term run is used almost synonymously. A related meaning of both "to run" and "to execute" refers to the specific action of a user starting (or launching or invoking) a program, as in "Please run the application."
convert is an external command first introduced with Windows 2000. [2] If the drive cannot be locked (for example, the drive is the system volume or the current drive) the command gives the option to convert the drive the next time the computer is restarted.
Instead of using standard .NET parameter types in P/Invoke method definitions (char[], string, etc.) it uses these interface classes in the P/Invoke function calls. For instance, if we consider the above example code, PInvoker would produce a .NET P/Invoke function accepting a .NET interface class wrapping the native char * pointer.
