中国DOS联盟

There are three batch files, A, B, and C.
A has the function of running B and C.
Want to realize the following function:
Run A.bat, Call B.bat. If B.bat runs successfully, then run C.bat.

In short, run in the order of A, B, C. C.bat should not run before B.bat is finished.

PS: Is there a concept of sleep in DOS?

I know but won't answer you. Didn't you read the "Newcomer Must-Read" post on the forum carefully when you registered?

　　The code in A.bat is just one line: call B.bat&&call C.bat；

　　What you mean by sleep is the meaning of delay?

If you want to implement that running A.bat calls B.bat and then runs C.bat after B.bat is completed.

　　Brother, do you mean that sleeping is delaying?

If there are calls to exe in B.bat, it won't work.

Sleeping means delaying, which is thread Sleep

If there are calls to EXE files in B.bat, it won't work. Sleep is about delaying, which is like thread Sleep.

　　If there are EXE files, you can use the start command to call them; start /min "" exefile.exe

　　Oh, this can be indirectly achieved by using the ping command to delay; ping 127.1 5 >nul 2>nul, which can delay for about 4 seconds.

The current situation is that there is something that calls an exe in B.bat. C.bat calls other bat files. A.bat still calls B.bat and C.bat (C should be executed after B is completed). Brother lxmxn, do you have any good methods?

Several batch processes can do things, and one batch process can also be completed. Just tell me what purpose you ultimately want to achieve.

The function of this batch processing is: First call an exe program (this takes time), and then run an external bat file (supplied by others). If the exe is not started properly and then the bat is run, it will report an error. So the bat must be run after the exe. I wonder if my expression lxmxn can understand it?

@echo off

start exefile.exe

ping 127.1 -n 5 >nul  2>nul

call batfile.bat

After the exe file runs, there is a delay of about 4 seconds, and then your bat file runs.

@echo off

start exefile.exe

ping 127.1 -n 5 >nul  2>nul

call batfile.bat

Hehe! First of all, thank you for lxmxn's reply.

I tried it and MS works. Just have some questions about -n 5. I checked ntcmds but couldn't figure it out. How is the time controlled? Can't it be controlled?

I'm stupid, hope lxmxn can give me some advice!

If it were me, I would CALL C.BAT in B.BAT, and then put the remaining A.BAT C/P to the end of C.BAT

:o You didn't understand it!

　　Re ivanisme:

The ping command has many parameters, among which there are the -n and -w parameters. The -n parameter indicates the number of sent ICMP packets, and the -w parameter indicates the time interval for timeout, meaning if the specified host is not reachable via ping, after how many seconds the packet will be re-sent. By default, the value of the -w parameter is 1000, which represents one second, and the -n parameter specifies the number of sent times. So specifying the -n parameter can determine the amount of delay. Using the principle of planting trees, if you want to delay for n seconds, then the parameter -n is specified as n + 1.

ping 127.1 -n 5 Here, "-n 5" means specifying the value of the -n parameter as 5, so it delays approximately 4 seconds.
