find "ati" new.ini && 7z.exe x "vga\ati.7z" -oc:\windows\drivers\vga\ati

There is a problem here:
In the NEW.INI file, there is a part where it's identifying the graphics card and extracting... %<0@V"s
FINDSTR: ignoring /c !B


GPT @pdati
MB) ~{1.|W{`u>
This will search for the incorrect ATI. I want to search for ATI chips, not this.
Is there a way to only search for the independent word "ATI" and not a word that contains the word ATI!?
The meaning may not be clear. Anyway, I just want to search for ATI alone!
Hope the expert can answer!

Is "\<ati\>" the meaning of a space?

I ran it but it didn't succeed!
findstr /ic:"<\ati\>" new.ini &&md 1
There is a NEW.INI in the directory with only 3 characters "ATI" in it, but I can't create the 1 folder. I don't know why!

Because you are too careless, take a close look at how my command format is written.

Oh, I was careless and missed a /r parameter. The correct one should be

findstr /irc:"\<ati\>" myfile.txt


That is, case-insensitive (/i), search for the regular expression pattern (/r) string (\<ati\>), where \< represents the start of a word and \> represents the end of a word.

Thanks, moderator lxmxn. The problem finally has a solution. I roughly understand the general idea, but I'm still a bit fuzzy about "what is the regular mode and the word boundaries".

Regular expressions are used to match fixed string formats.

For example, it is stipulated that in a string, it can only be numbers, only letters, or a combination of numbers, letters, and underscores (_). Even, there can only be 3 numbers followed by 2 letters, etc., which is very flexible. Does it mean that it can only be ATI and nothing else? I wonder if the understanding is correct?

\<represents the front boundary of a word, and \> represents the back boundary of a word. As for this sentence, I can't understand it.
