cmd /C是什么意思?

我能理解cmd，但不能理解cmd /c。我试图从当前调用一个java程序，我使用Runtime.getRuntime().exec("cmd /C java helloworld");有我的怀疑。

/C执行字符串指定的命令，然后终止。

你可以通过输入cmd /?来获得所有的cmd命令行开关。

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.
