China DOS Union

Does any sir know, in a batch file, how to judge whether the system date of the current computer is equal to a certain date string, and if it is, run a certain file or command? Waiting for good news! I don't want to use external tools!

There are ways, but......

It's还算 okay.

Specific writing, I can't write it now.

But the idea is like this.

It's impossible to use the time and date commands because they require you to enter new ones to replace.

We can create a directory (such as md aa), and then judge what the creation date of this directory is.

I think these commands should be used.

md
dir
more
find
>
|
if errorlevel=.......

.......

I'm really sorry...... I forgot.

Dude, could you please recall it?

I really can't remember, dude.

I can only tell you the idea.

First, immediately create a directory (because it's more troublesome to create a file), then DIR can see the creation date of the directory.

Then use if ..... (to judge whether the strings are equal... ... if there are three usages... ... one of them... ...)

Then use more, find, and dir, and at the same time, use | (pipe), > (redirection) to write these three commands into one,

Mainly to judge whether the period of the directory you just created (displayed on the screen with dir) is equal to the string after your if... ...

......

If you can get a DOS manual, it will be easy.

Maybe it can be a little helpful.

Really can't remember.

Don't want to use external tools, just write a small program by yourself. This problem is very easy to implement with BASIC language.

The specific examples can be found in the program examples provided by the BASIC program. There are corresponding example programs for MS-BASIC version 7.1 and QUICK BASIC version 4.5.

Re ztb888:

This problem is not very difficult, and there are quite a number of solutions, which are based on different systems and different requirements. The complexity and skill level are also different. If we really want to describe them in detail, it can be tens of thousands of words. There are many posts about dates and times on this site. You can use the search function to browse roughly, understand various solutions, and then determine your requirements and tell us so that we can solve the problem targeted.

I'll show an example:

remind.bat
-----------------
@echo off
ver|date|find "05-21">%TEMP%\$$$temp1
copy %TEMP%\$$$temp1 %TEMP%\$$$temp2>NUL
if exist %TEMP%\$$$temp2 goto remind
goto end

:remind
echo --------------------------------
echo Today is important day!
echo --------------------------------

:end
del %TEMP%\$$$temp1
del %TEMP%\$$$temp2

I think the method the moderator said is very good, but it would be better if it's simpler. And according to the moderator's meaning, it seems that can't we copy empty files?
MD $$$###
DIR $$$###|FIND "05-22">NUL
IF NOT ERRORLEVEL 1 GOTO TRY
::今天不是你想要的日子
GOTO END
:TRY
::今天是真正的日子，现在你可以做你想做的事情
:END

Files that are empty can't be copied?

Re Roy:

The method you used seems to have been developed when the DOS low-version FIND didn't generate ERRORLEVEL. Now there's no need for that because most people are using high versions, and "not copying empty files" should be considered an unstandardized detail of DOS, which may be canceled in some versions.

Moreover, in localized or DOS systems that haven't solved the Y2K problem, there are potential issues with this program. For example, I want to detect whether it's May 4th, using ver|date|find "05-04">%TEMP%\$$$temp1 may confuse various states such as April 2005, May 2004, and April 5th, etc.

@echo off
setlocal enabledelayedexpansion
set mm=%date:~5,2%
set dd=%date:~8,2%
if %mm% lss 10 set mm=%date:~6,1%
set /a od=!mm!-1
if !od! lss 10 set rq=0!od!
set cw=%date:~0,4%.!rq!
set /p a=Please enter the name of the area to query (just the first letter of the area):
net use z: /delete
net use z: \\10.10.103.7\Upload wang /user:administrator
dir z:\Monthly Report\%cw% |find "%a%"
if %errorlevel%==0 goto abc
goto end
:abc
mshta vbscript:CreateObject("Wscript.Shell").popup("The monthly report of the area you inquired has been submitted!",7,"System Prompt!",64)(window.close)
exit
:end
mshta vbscript:CreateObject("Wscript.Shell").popup("The monthly report of the area you inquired has not been submitted, please urge to complete it!",7,"System Prompt!",64)(window.close)
exit

I wrote this personally, hope it helps
