FOR /F ["options"] %%i IN ("string") DO command
FOR /F ["options"] %%i IN ('command') DO command 中的FOR /F ["options"] %%i IN ('command') DO command 不懂能告诉一下举些例子好吗谢谢版主了 o(∩_∩)o...

c:\>call/?
Calls one batch program from another.
CALL [drive:][path]filename [batch-parameters]
  batch-parameters Specifies any command-line information required by the
                  batch program.
If Command Extensions are enabled CALL changes as follows:
CALL command now accepts labels as the target of the CALL.  The syntax
is:
CALL :label arguments
A new batch file context is created with the specified arguments and
control is passed to the statement after the label specified.  You must
"exit" twice by reaching the end of the batch script file twice.  The
first time you read the end, control will return to just after the CALL
statement.  The second time will exit the batch script.  Type GOTO /?
for a description of the GOTO :EOF extension that will allow you to
"return" from a batch script.
In addition, expansion of batch script argument references (%0, %1,
etc.) have been changed as follows:

%* in a batch script refers to all the arguments (e.g. %1 %2 %3
      %4 %5 ...)
Substitution of batch parameters (%n) has been enhanced.  You can
now use the following optional syntax:
       %~1       - expands %1 removing any surrounding quotes (")
      %~f1       - expands %1 to a fully qualified path name
      %~d1       - expands %1 to a drive letter only
      %~p1       - expands %1 to a path only
      %~n1       - expands %1 to a file name only
      %~x1       - expands %1 to a file extension only
      %~s1       - expanded path contains short names only
      %~a1       - expands %1 to file attributes
      %~t1       - expands %1 to date/time of file
      %~z1       - expands %1 to size of file
      %~$PATH:1 - searches the directories listed in the PATH
                     environment variable and expands %1 to the fully
                     qualified name of the first one found.  If the
                     environment variable name is not defined or the
                     file is not found by the search, then this
                     modifier expands to the empty string
The modifiers can be combined to get compound results:
      %~dp1    - expands %1 to a drive letter and path only
      %~nx1    - expands %1 to a file name and extension only
      %~dp$PATH:1 - searches the directories listed in the PATH
                     environment variable for %1 and expands to the
                     drive letter and path of the first one found.
      %~ftza1    - expands %1 to a DIR like output line
In the above examples %1 and PATH can be replaced by other
valid values.  The %~ syntax is terminated by a valid argument
number.  The %~ modifiers may not be used with %*

@echo off
set "file=C:\Program Files\Internet Explorer\HMMAPI.DLL"

for /f "delims=" %%a in ("%file%") do echo %%~dpa
rem   上面这个就是显示驱动器号和路径

for /f "delims=" %%a in ("%file%") do echo %%~nxa
rem   上面这个就是显示文件名和文件扩展名

for /f "delims=" %%a in ("%file%") do echo %%~fsa
rem   上面这个就是显示有短名的完整路径名，注意这里是短名
rem  如c:\progra~1\intern~1之类的

rem  in前面是%%a,后面就用%%~fsa,如果前面是%%i那后面就用%%~fsi
pause

谢谢慢慢研究呵呵谢谢诶帮忙

作者: sihonghong20061 时间: 2008-8-1 08:11 标题: 回复 5楼的帖子

版主能不能帮我讲解一下FOR /F ["options"] %%i IN ('command') DO command 中的 ('command')

顺便举些例子 for的其他命令我懂了就这个谢谢诶了

其它的都懂了就这个不会？
其实一样简单的呀。

@echo off
for /f "tokens=1-3 delims=- " %%a in ('echo %date%') do echo %%a年%%b月%%c日
pause
复制代码

在上面代码中，FOR会先执行echo %date%，然后把它执行的结果传递给FOR，FOR
再以选项delims=- 来分隔它

大概就是这样子的啦，多看看别人的代码，自己写些简单的代码慢慢的就会了
