通过

rem

记录脚本、批处理或 config.sys 文件中的注释。 If no comment is specified, rem adds vertical spacing.

Note

此命令在命令行解释器内部，cmd.exe。

Syntax

rem [<comment>]

Parameters

Parameter Description
<comment> 指定要作为注释包含的字符字符串。
/? 在命令提示符下显示帮助。

Remarks

  • The rem command doesn't display comments on the screen. To display comments on the screen, you must include the echo on command in your file.

  • 不能在批处理文件注释中使用重定向字符（< 或 >）或管道（|）。

  • Although you can use rem without a comment to add vertical spacing to a batch file, you can also use blank lines. 处理批处理程序时，将忽略空白行。

Examples

若要通过批处理文件注释添加垂直间距，请键入：

@echo off
rem  This batch program formats and checks new disks.
rem  It is named Checknew.bat.
rem
rem echo Insert new disk in Drive B.
pause
format b: /v chkdsk b:

To include an explanatory comment before the prompt command in a config.sys file, type:

rem Set prompt to indicate current directory
prompt $p$g

若要提供有关脚本执行的作的注释，请键入：

rem The commands in this script set up 3 drives.
rem The first drive is a primary partition and is
rem assigned the letter D. The second and third drives
rem are logical partitions, and are assigned letters
rem E and F.
create partition primary size=2048
assign d:
create partition extended
create partition logical size=2048
assign e:
create partition logical
assign f:

对于多行注释，请使用条件执行：

  Rem/||(
    The REM statement evaluates to success,
    so these lines will never be executed.
    Keep in mind that you will need to escape closing parentheses
    within multi-line comment blocks like shown in this example. ^)
