Check the specified folder. If a line in a TXT file inside it is "HHHHHHH", immediately delete that file. If "HHHHHHH" appears in other lines, it can be ignored. The following code doesn't seem to solve my problem. Who is willing to help take a look? Thanks set old=d:\test set SRT1=HHHHHHH for /f "delims=" %%c in ('dir /b /s /a-d "%old%\.txt"') do ( for /f "delims=" %%d in (%%c) do ( if %%d==%STR1%* del %%c))

Is my question is too simple or not explained clearly? Suppose there are many TXT files in a directory: File A: 123 456 123456 File B: 123 888 88456 If a specific string 456 is given, then file A should be deleted because the second line is exactly 456. And file B does not need to be deleted because 456 is only part of its third line. Can anyone help? Or give a hint, I'm very new to this...

If you are using the DOS system, its for command does not support /f.

To be precise, it's that the FOR command in COMMAND that comes with DOS doesn't support the /f parameter. But if you use 4DOS as the command interpreter, it does support it.
