Records comments (remarks) in a batch file or CONFIG.SYS. If no comment is specified, rem adds vertical spacing.
For examples of how to use this command, see Examples.
Specifies a string of characters to include as a comment.
Displays help at the command prompt.
- The rem command does not display comments on the screen.
You must use the echo on command in your batch or CONFIG.SYS
file to display comments on the screen.
- You cannot use a redirection character (< or
>) or pipe (|) in a batch file comment.
- Although you can use rem without a comment to add
vertical spacing to a batch file, you can also use blank lines.
Blank lines are ignored when a batch program is processed.
The following example shows a batch file that uses remarks for comments and for vertical spacing:
@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 your CONFIG.SYS file, add the following lines to CONFIG.SYS:
rem Set prompt to indicate current directory prompt $p$g
