How would you make the batch file search for a string in a batch file, then if the string exists , it does the specified command.

BC_Programmer · « **Reply #1 on:** January 18, 2009, 07:40:05 PM »

use find command and errorlevel.

BatchFileCommand · « **Reply #2 on:** January 18, 2009, 07:44:41 PM »

So would this work.

Code: [Select]

find /i "string" filename
if errorlevel 0 do echo string unfound

Ok, "no".

I can see why.

So can you if you read the error message.

You can roll your eyes all you like. Attitude like that will get you a whole bunch of help, wise guy.

BatchFileCommand · « **Reply #7 on:** January 19, 2009, 11:50:13 AM »

Unfortunately I turn echo on and there is no error message. I just took a random guess with the errorlevel.
Besides, Dias, why are you always this "I know everything" guy who has no "patience" .

I am not. I just respond badly to lazy people.

computers.txt contains the text 'bb'

Code: [Select]

@echo off
find /i "bb" computers.txt
if errorlevel 0 do echo string unfound

I saved it as tme.bat

Code: [Select]

C:\>tme

---------- COMPUTERS.TXT
bb
'do' is not recognized as an internal or external command,
operable program or batch file.

Oh yeah, I took away the do shortly after the first post. Should've edited and took that out. So, any other reason it shouldn't be working?

It depends what you mean by "working".

You have the logic the wrong way around. If errorlevel is 0 that means there was no error, that is, the string was found, not "unfound", (did you mean not found?)

BatchFileCommand · « **Reply #11 on:** January 19, 2009, 01:22:18 PM »

Oh, I thought if errorlevel was 0 there was an error

.
So I need to add a bit more. Would it matter if I have the .txt or not?

Code: [Select]

find /i "text" file
if not errorlevel 0 (echo found) else (echo unfound)
pause>nul

It always says found. I've tried this with the extension on and off the file name.

Dias de verano · « **Reply #12 on:** January 19, 2009, 01:54:28 PM »

You must always use the full file name including extension.

This works

Code: [Select]

find /i "text" filename.ext
if %errorlevel% EQU 0 (echo found) else (echo not found)

BatchFileCommand · « **Reply #13 on:** January 19, 2009, 02:23:24 PM »

Finally! It works

.

BC_Programmer · « **Reply #14 on:** January 19, 2009, 07:12:12 PM »

awwwww. Darn. I was reading the thread and hoping BFC got contrexed. But he isn't worthy of a Contrexing. As entertaining as they are, they likely take some effort.

Now he's gonna ask- "whats contrexing?"

BatchFileCommand · « **Reply #15 on:** January 19, 2009, 07:23:08 PM »

The reason I may of seemed a bit "feeble-minded" is because I was quite unfamiliar with errorlevel. Contrexing is a word that doesn't exist

. Can't fool me there. I checked Wikipedia. 4 different dictionaries. I googled it. It doesn't exist. So what's the meaning of the meaningless word contrexing.

BC_Programmer · « **Reply #16 on:** January 19, 2009, 07:29:48 PM »

har har har. it's a secret word. Look in the forum archives.

it's standard procedure for a error flag to me a number, and 0 means success. each different number means a different error. That way, one can easily check success by determining if the error code is 0.

I wasn't around when Contrex was, but I think I know how it works...

Contrexing (proper-verb=must have capital) is the act of flaming another user, in the way that Contrex would have.

(Is that right?)

Really? Then I have never met him(/her). The way you and Ivy and other members were talking about him (or her) made it sound like (s)he left a while ago.

Flaming is just gratuitous rudeness; contrexing is usually deserved.

So, Contrexing is flaming another person because you think you can judge if they deserve it.

From what I understand, Contrexing is flaming another person BECAUSE they DO deserve it, not flaming someone because you hate their idea.

Idea has nothing to do with it

Roughly speaking, a contrexing is a rebuke for attitude or bumptiousness or rudeness or severe lack of respect or being a troll.

ahhh, yes, Trolls get something they don't expect. They are begging for Flaming, and yet, POOF! they get a contrexing! what you do, is you make it bullet-proof. You take each point given by the poster and give a well-researched, immaculately drawn, bulletproof counterpoint. If you see any direct personal insults that seem out-of-context, then the contrexer is likely a trainee in the fine art of Contrexing. Although, the rules if Contrexing border the land of Flames, so one or two "yo mamas" might slip out even from the most season professional.

Contrexing is not A rule, but it HAS a (almost) unspoken set of rules that you must follow to be successful in Contrexing.

The definition advanced because you refused to understand the previous explanations.
