You can set the time for the "find" clause based on your own needs, or use the parameter % 1 instead. You can also change the time to date to implement the scheduled execution function. ------------------------------ Quote: : Current. bat @ Echo off Echo Haha, it's the time to go !! : Timer. bat @ Echo off : Start Echo. | time | find "10:30:00"> Run. bat Choice/C: Y/T: Y, 59/n> NUL Call run. bat Goto start   ASCII assembly code, latency precision is 0.001 seconds, applicable platform for MS-DOS/Win9x/winnt. German Herbert kleebauerprovided a general solution to achieve latency through asciiassembler indirectly using a sleep.exe program. This program is divided into dos and win modules, respectively calling DOS system interruption services and windowsapi.

Pause, delay, wait, and sleep) 1) For + set + if, time precision is 0.01 seconds, applicable platform is winnt/2 k/XP/2003. Use the for variable % time % to parse and coexist for two time points % start % and % Now %. Then use set/a to calculate the time difference between the two time points, finally, use if to determine whether the time difference has reached the set pause time.

You can use this batch.

I wonder if you can do it ?? Eg: Echo "% ~ Dp0 "> test. bat Try: Echo "% ~ Dp0 "> test. bat Determination of the extension in the file name 7. How can I determine the file Suffix in batch processing? Achieve the following effects. If "% 1" = "*. dll" Goto DLL If "% 1" "=" *. inf "Goto INF 1. If the file name refers to a single file that exists and does not contain the specified path, you can use the following solution: Code: [copy to clipboard] -------------------------------------------------------------------------------- For % x in (*. dll) do if exist "% 1" Goto DLL For % x in (*. inf) do if exist "% 1" Goto INF 2. If the file name refers to a single file, but it does not exist and does not contain the specified path, you can use the following solution: Code: [copy to clipboard] -------------------------------------------------------------------------------- If not exist % Temp % \ _ getext _ \ nul md % Temp % \ _ getext _ Echo _ getext _> % Temp % \ _ getext _ \ % 1 If exist % Temp % \ _ getext _ \ *. dll goto DLL If exist % Temp % \ _ getext _ \ *. inf goto INF 3. If the application environment of the program is an NT-series command line and the file name contains only one period to separate the primary file name and extension, you can use the following solution: Code: [copy to clipboard] -------------------------------------------------------------------------------- For/F "delims =. tokens = 2" % x in ("% 1") do set _ ext = % x If "% _ ext %" = "DLL" Goto DLL If "% _ ext %" = "inf" Goto DLL   Directory existence determination This seems to be a very simple problem. In most of the batch processing processes I have seen and compiled, the directory determination uses this classic format: If exist directory \ NUL command argument (s) It can be said that the creator of this technique did have a profound research on dos. At least he found the complex and subtle relationship between the device management mechanism represented by NUL and the file management mechanism, NUL devices and. and .. can be referenced directly in most paths without generating system errors. However, just as NUL cannot be referenced in the root directory (which is modified in NT cmd), NUL also has its limitations. When we load doslfn in the msdos7.10 environment to support long file names, some bugs in doslfn will escape the reference of \ NUL and the file will be regarded as a directory. Quote: C: \> echo.> test.txt C: \> If exist test.txt \ NUL echo exist dir "test.txt" Exist dir "test.txt" C: \>   If this is just a problem with doslfn, we can disable doslfn and then transfer the test position to the CD. Because the CD has a unique File System (CDFs) and \ NUL references are invalid, the directory still cannot be identified, but the file will not be mistaken as a directory. Quote: E: \> DIR/AD/B Boot Dos71 E: \> If exist boot \ NUL echo exist dir "Boot" E: \>   Let's move to the newCMD @ WINXPIf the directory name contains spaces, it cannot be identified by long file names. Quote: C: \> MD "my test" C: \> if not exist "my test" \ nul echo not exist "my test" Not Exist "my test" C: \> if not exist "my test \ NUL" echo not exist "my test" Not Exist "my test" C: \>   Determination of directory existence Use if exist directory \ NUL command argument (s) As long as the directory contains spaces, no matter how it is matched incorrectly. In actual application, the following methods are generally used: Code: [copy to clipboard] -------------------------------------------------------------------------------- MD "my test" Cd "my test" & Echo exist directory "test" This will be very accurate, but it also has a disadvantage, that is, it will enter its Directory Selection of defense characters when referencing paths in Environment Variables   Quote: Another issue related to this is the defensive character after the PATH variable. When we use environment variables to reference a path, we usually directly reference it, for example: % Temp % \ _ temp. bat But there is a problem: If % Temp % is the root directory of a drive, such as c: \, then the above reference will become: C: \ _ temp. bat The double diagonal lines appear in the path, which will cause syntax errors in the MS-DOS and Win9x, so someone adopted the method of adding a period after the variable, namely: % Temp %. \ _ temp. bat In this case, if % Temp % is the root directory, the reference result is: C :\. \ _ temp. bat, if it is not the root directory (such as c: \ Temp), it is c: \ temp. \ _ temp. BAT. This utilizes the ambiguity of a sentence in different usage: In the previous usage, it indicates the current directory, and the current directory under the root directory is still the root directory; in the last usage, it indicates the delimiter between the main name and the extension in the directory name. Because there is no actual extension after the period, c: \ temp. it still indicates the c: \ temp directory. However, this brings about a new problem: what if a special reference character of the relative path appears in the path? For example, if % Temp % indicates the current directory or the .. of the upper-level directory, the reference of % Temp %. \ _ temp. Bat becomes: .. \ _ Temp. bat or... \ _ temp. bat This is obviously not the result we need. What should we do? The answer is in your hands.
