Que signifie cmd/C?

Question

Je peux comprendre cmd mais pas cmd /c. J'essayais d'invoquer un programme Java à partir du courant pour lequel j'utilise Runtime.getRuntime().exec("cmd /C java helloworld"); Il se pose mon doute.

Answer 1

/C Exécute la commande spécifiée par la chaîne, puis se termine.

Vous pouvez obtenir tous les commutateurs de ligne de commande cmd en tapant cmd /?.

Answer 2

CMD.exe 

Start a new CMD shell 

Syntax 
     CMD [charset] [options] [My_Command] 

Options  

**/C  Carries out My_Command and then 
terminates** 

De l'aide.

Microsoft Windows XP [Version 5.1.2600] 
(C) Copyright 1985-2001 Microsoft Corp. 

C:\>cmd /? 
Starts a new instance of the Windows XP command interpreter 

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF] 
    [[/S] [/C | /K] string] 

/C  Carries out the command specified by string and then terminates 
/K  Carries out the command specified by string but remains 
/S  Modifies the treatment of string after /C or /K (see below) 
/Q  Turns echo off 
/D  Disable execution of AutoRun commands from registry (see below) 
/A  Causes the output of internal commands to a pipe or file to be ANSI 
/U  Causes the output of internal commands to a pipe or file to be 
     Unicode 
/T:fg Sets the foreground/background colors (see COLOR /? for more info) 
/E:ON Enable command extensions (see below) 
/E:OFF Disable command extensions (see below) 
/F:ON Enable file and directory name completion characters (see below) 
/F:OFF Disable file and directory name completion characters (see below) 
/V:ON Enable delayed environment variable expansion using ! as the 
     delimiter. For example, /V:ON would allow !var! to expand the 
     variable var at execution time. The var syntax expands variables 
     at input time, which is quite a different thing when inside of a FOR 
     loop. 
/V:OFF Disable delayed environment expansion.
