Extract Information from TXT files - batch-file

Question

I am looking at creating a batch file that extracts information out of a txt file from the last 3 months of log files, and out puts with the following information:
Computer name taken from file Path:
\\Server\e$\Users\\**COMPUTER_NAME**\path\search_file.txt
Search for total number of occurrences in a file (Nice to have - Not MUST)
Time of occurrence:
File being searched has a format of this when found:
09:24:08:17 (WS:PED:RunRequest)
Response: (0) None
Error : -2
So...
COMPUTER_NAME
Number of occurrences found
Time of occurrence i.e. 09:24:08:17
I have this as a start:
#echo off
echo.
echo Searching for all Error : -2...
setlocal enabledelayedexpansion
for %%a in (\\Sc0320svr0001\e$\Users\SC0320POS0003\E2ELOGS\ped_20140812_092355.dbg) do
(
set found=false
for /f "skip=2 tokens=*" %%b in ('find "Error : -2" "%%a"') do (
if "!found!"=="false" (
echo %%b >>output.txt
set found=true
)
)
)
With this I extract only the "Error : -2", and there could be MULTIPLE instances within.
Found the batch to do a count number:
#find /c /i "Error : -2" "\\Sc0320svr0001\e$\Users\SC0320POS0003\E2ELOGS\*.dbg" >>output.txt
However ONLY looking to output if greater than zero.
Portion of the file:
09:23:55:68 (WS:PED:OpenHandler)
Exit
09:23:55:76 (WS:PED:RunRequest)
Request: (1) Check PED status
09:23:55:86 (WS:PED:Write)
Data: 97
09:24:08:08 (WS:PED:Write)
Error: 30
09:24:08:17 (WS:PED:RunRequest)
Response: (0) None
Error : -2

This processes only one file...Check if it is doing the job:
#echo off
setlocal enableDelayedExpansion
set file_txt=apple.txt
set "current_line="
set "prev_line="
set "prev_prev_line="
set counter=0
for /f "tokens=* delims=" %%a in (%file_txt%) do (
rem echo -%%a-
if defined prev_line (
set prev_prev_line=!prev_line!
)
if defined current_line (
set prev_line=!current_line!
)
set "current_line=%%~a"
if "!current_line: =!" EQU "Error:-2" (
set /a counter=counter+1
echo(
echo Error -2 found
echo in %file_txt%
echo time is !prev_prev_line!
echo responces !prev_line!
echo(
)
)
echo total count %counter%
endlocal
EDIT. process multiple files
#echo off
setlocal enableDelayedExpansion
:: separate the file names with ;
set files_to_process=apple.txt;banana.txt;pear.txt
set "current_line="
set "prev_line="
set "prev_prev_line="
set counter=0
for %%f in (%files_to_process%) do (
for /f "tokens=* delims=" %%a in (%file_txt%) do (
rem echo -%%a-
if defined prev_line (
set prev_prev_line=!prev_line!
)
if defined current_line (
set prev_line=!current_line!
)
set "current_line=%%~a"
if "!current_line: =!" EQU "Error:-2" (
set /a counter=counter+1
echo(
echo Error -2 found
echo in %file_txt%
echo time is !prev_prev_line!
echo responces !prev_line!
echo(
)
)
)
echo total count %counter%
endlocal
