[marcorocchini]

Hi, but pleae be patient because I'm a cat


I need to find via batch file an example.txt file that contain

%use_choice%

and replace this string so that it becomes

rem %use_choice%

how can I do? thanks

I know the answer, but I'm not going to post it because you keep insisting on your "cat" stupidity. Please grow up.

Open Notepad and click on edit/replace.

Get a command line text editor like sed and learn to use it:

sed s/"%%use_choice%%"/"rem %%use_choice%%"/ input.txt >output.txt

[marcorocchini]

jagabo for kindness what sed.exe are you using? can you give me that are you using?

[teodz1984]

Google sed windows

I've already done hundreds of attempts and I'm not able. I'm a stupid cat or not? obvious that I already tried with google

[marcorocchini]

Get a command line text editor like sed and learn to use it:

sed s/"%%use_choice%%"/"rem %%use_choice%%"/ input.txt >output.txt

exactly I don't know for what reasons I cannot but if I try this but suppose a bbb.txt file locate in v:\autogen and simply containing this text:

%use_choice%

If I manually execute from CMD this:

v:\automazioneclip\system\sed\sed.exe -i "s/%use_choice%/rem %use_choice%/g" v:\AutoGen\bbb.bat

supposing sed.exe locate in v:\automazioneclip\system\sed\ (but nothing change also if located in v:\AutoGen or other folders)

it works (the bbb.txt file is overwrite but becomes rem %use_choice%)

But I need to work already inside a batch, so for example:

when I have a simple.bat file that contain:

v:\automazioneclip\system\sed\sed.exe -i "s/%use_choice%/rem %use_choice%/g" v:\AutoGen\bbb.bat

and I launch it as. bat ... it don't works

the same commandline out of a batch, strangely don't works


probably inside a batch the % % expression is referred alwais to a variable

[teodz1984]

% is used by windows command line for environment variables.. jagabo will explain next post

[jagabo]

The percent sign in a batch file has a meaning, it's not just a text character. If you want a literal percent sign you have to "escape" it, %%, just like in my earlier post.

[teodz1984]

v:\automazioneclip\system\sed\sed.exe -i "s/%%use_choice%%/rem %%use_choice%%/g" v:\AutoGen\bbb.bat

just use a text editor to do the replacement .https://notepad-plus-plus.org/
