Batch file for findstr

I am no amateur in batch scripting...With help about findstr from the command line, i was able to make the findstr work for me in the commandline.

My command is: findstr /r /i /m "AddImgIfNextIsSame" e:\dap\dapcore\ho\v97\mstrres\ddtlib\*.* >> H:\dap\kk2.txt
and it works fine.

Two things I am struggling with are:

1) How to add another directory to this findstr command and make it work. I tried:
findstr /r /i /m "AddImgIfNextIsSame" /d:e:\dap\dapcore\ho\v97\mstrres\ddtlib\*.*;e:\dap\dapcore\ho\v10\mstrres\ddtlib\*.* >> H:\dap\kk2.txt
but it gives cannot open the directory error.

2) How to make this work from batch file. I put the exact same command in a notepad and renamed it as .bat file, but is not working.

Pls suggest.

I don't believe that you can specify multiple files. You can include wildcards in the one file specification to process more than one files, but that doesn't help you. I'd issue two findstr commands in a batch file (in any form you want).

Good Luck,

I didn't notice that D parameter so, your processing should work great with one line as follows:

findstr /r /i /m /D:e:\dap\dapcore\ho\v97\mstrres\ddtlib;e:\dap\dapcore\ho\v10\mstrres\ddtlib  "AddImgIfNextIsSame" *.* >> H:\dap\kk2.txt

You could make it into a batch file by using notepad and adding this line:

@findstr /r /i /m /D:e:\dap\dapcore\ho\v97\mstrres\ddtlib;e:\dap\dapcore\ho\v10\mstrres\ddtlib  "AddImgIfNextIsSame" *.* >> H:\dap\kk2.txt

Thanks Steve, it works great with one line in the commandprompt.

However, the batch file is not working..as if it is processing forever...it never ends and no output also..

You could try to remove the redirection from the batch file to see what is occuring:

@findstr /r /i /m /D:e:\dap\dapcore\ho\v97\mstrres\ddtlib;e:\dap\dapcore\ho\v10\mstrres\ddtlib  "AddImgIfNextIsSame" *.*

I notice that you're using the '/r' option which enables the use of regular expressions in your search criteria.  In most other tools (perl, php, etc.) enabling regex matching can really slow performance as opposed to plain text matching.

In your case, you are not using a regex search string so I would omit the /r option to see if the performance improves at all.

Also, if you use findstr on each directory individually, are you still seeing the same performance problem? (when you add the two times together?)
