I'd like to replace string with new one in *.srt file. I found similar solution created by M2 here: http://www.computing.net/answers/pr... ---------------------------------------------------- @echo off > newfile setLocal EnableDelayedExpansion for /f "tokens=* delims= " %%a in (oldfile) do ( set str=%%a set str=!str:oldtext=newtext! echo !str! >> newfile ) ----------------------------------------------------- Is it possible: 1. to make upper solution case sensitive, 2. to read from file a list of strings which need to be replaced at once, instead of replaceing strings one by one, and 3. in case that in "oldfile" exist more than one same string, just to find the first and replace with new one (the others except the first one have to be left unchanged). Thanks in advance.

1. yes, i think it's possible using find.exe, but it will impact on the performance severely when replacing string in large file. 2. use for loop in list of strings eg. set list=this is a list of strings for /f "tokens=*" %%a in (file.txt) do ( set str=%%a for %%b in (%list%) do set str=!str:%%b=! ) 3. use goto:breakAloop when match found i would suggest using vbscript that support case sensitive replace function. vbBinaryCompare 0 Perform a binary comparison. vbTextCompare 1 Perform a textual comparison.

First off all, my apology about my voute in which I said that your answer is the best, the corect is that it is the worst answer I've ever got! Everyting in your answer is wrong!!! Why are you dealing with something that you understand less than me?

check your tone. you are asking for help here. the beggar cannot be the chooser.

you know why, because you are so f****** dumb to implement my suggestion into a working script.

I am asking for help only those people who can help. I don't need so-called help. If you can help, then help, but don't take with your "suggestions" place those pearsons who can know to give real answer. So if I ask: "Is it possible to make upper solution case sensitive?", do you think that your answer: "Yes, i think it's possible using find.exe..." is really what I expected? Maybe, here is someone really f**... d**..., but I'm absolutely sure that guy is not me!

think carefully, the dumb guy is you. if you had reply nicely, i'll write and show you the whole working script either in batch or vbs. oops, or you brain is too dumb to think.
