Solve : searching for a string in dos window output?

Answer»

Hello everybody,

i'm an old-renewed user of the old too msdos.

Actually i'm facing the PROBLEM of launching an application when the output of another application contains a particular string.

In my case i launch the application "A". When in the output i read "running" i want to launch application "B".
When the log file written by "B" contains the "running" string i launch application "C".

Could this be done?

thanks a lot for any hints

ByeYou would have to redirect the output of each application with pipes:

Code: [Select]@echo off
appA.exe | findstr "running" > temp.tmp
for /F %%a in (temp.tmp) do (
if '%%a'=='running' goto appB
)

:appB
appB.exe
del temp.tmp
findstr "running" Blog.txt > temp.tmp
for /f %%b in (temp.tmp) do (
if '%%b'=='running' goto appC
)

:appC
del temp.tmp
appC.exe

Hope this helps
,Nick(macdad-)That code is going to arrive at the labels :appB and :appC whatever happens.
Thats what's its supposed to do:

This code will go to label :appB, whether or not the word 'running' is found, so what is the point of the IF test?

it is not supposed to do that
it should go do label appb only if i see in the console output the "prograM is running" string.
i would prefer to read to console because the output to teMp file, after a while, stops and i think it is redirect to another file. I've tried with the /g OPTION but i do not understand how to insert the "/" for the console. I tried everything with any result.

Anyway if you have a link with a clear explanation of batch coMMands it would help a lot.

Thanks

Let me make sure I have this right. You launch A and it produces screen output, which might, or might not, include the word "running"? Is that right? Or do you mean, it will produce the word "running" sooner or later, and you want to wait until that happens?

You see, that word "when" is niggling away in my mind. Are you aiming to monitor the logfile while program B is running, and when you once again see the word "running" in it, then you launch program C?

And please, why are you being all coy and calling the programs A, B and C? Why is it such a big secret what you are trying to do, what the programs are called, and what they do? How do you expect any serious help if you just give part of the needed information?
The logic for batch files can be LIKE this:
Code: [Select]If thing == true goto NotFalse
goto IsFalse
:NotFalse
echo It was ture.
goto AllDone
:IsFalse
echo Yes, it was not ture.
:AllDone
You use the goto to create code blocks.

sorry for my bad english. I mean that as soon as i see in the logfile the phrase "program B is running" i want to launch the program C

No secrets at all :-) it's just for semplification. Anyway program A is Bea weblogic server, B is a server-side code running on bea weblogic and program C is a TESTING unit that runs on B.

That's all

Actually i'll try Geek solution. The only open point is how to use findstr on console without reading the temp file.

Thanks a lot

Byeok

i went forward

now my problem is here

appA.bat | findstr "running" > temp.tmp

until appA finishes (and it does not do it) the batch does not continue

Actually appA = run server_admin

I've tried all of these

start run server_admin >temp.tmp
run server_admin | findstr /c:"RUNNING mode" >temp.tmp
call (run server_admin) | (findstr /c:"Server started in RUNNING mode")> temp.tmp

don't know how to try
So how can i launch a bat file (in my case run.bat), get it's output to a file and continuing searching in this file before run.bat finishes?

like this:

run server_admin >temp.tmp

:wait_admin_console
findstr /c:"RUNNING mode" temp.tmp
if not ErrorLevel 1 goto continue

goto wait_admin_console

:continue
...

thanks a lot
bye
