Skip characters in txt i/o batch script?

[jerryh91]

I'm trying to do a line by line comparison of 2 .txt files. But the problem is for the first file I'd like to start comparing line by line after the first 9 characters of each line of the first 10 lines in the 1st file with the second file. I read somewhere that you can extract substring, but I've only seen format where you have to specify the length of the substring (~start,length), for mine each line has a different length. How do I accomplish this?

Code: Select all

< !logPath! (
 FOR /F "tokens=*" %%A in (%refLogPath%) DO (
      set logLine=
      set /p logLine=
      set refLogLine=%%A
      echo !logLine!
      echo !refLogLine! 

      REM check logLine against refLogLine(ENG-REF.log)
  REM skip 1st 9 chars of each line
      if NOT !logLine!==!refLogLine! (

     set flag=false
         echo !logLine!
 ) else (
 set flag=true
  echo !flag!
)

Do you only want 10 lines compared? What kind of info do you need regarding any differences?
