Batch File to display file name and then certain lines in the files - date

Question

I have a folder of .log files where the content of each file has multiple lines of the following format:
yyyy/mm/dd, hh:mm:ss, ComputerName, IPAddress, stuff, stuff
I would like to create a batch file to parse through the .log files and create the following output for any line in a file where ComputerName starts with "XPLT":
filename,yyyy/mm/dd,ComputerName,IPAddress
And preferably, I'd like to only look at files with a modified date within the last 30 days.
So far, I've only gotten the following code which doesn't even work and doesn't even include the file modified date and parsing by ComputerName. Looking for help because I've just not done this very much, and I can't find a good example online.
Echo EID,Date,PCName,IPAdd>CitrixLogs.csv
setlocal enabledelayedexpansion
for /f "tokens=1,3,4" %%i in ('dir /b "C:\LogFiles\*.log"') do (
echo %%i,%%j,%%k,%%l>>CitrixLogs.csv
)

Answer 1

I'd use a bit of FINDSTR magic:
set LOG_DIR=c:\logfiles
for /f "tokens=1-7 delims=:," %%L in ('%SystemRoot%\System32\findstr.exe /r /c:"^[0-9][0-9][0-9][0-9]/[0-9][0-9]/[0-9][0-9],[0-9][0-9]:[0-9][0-9]:[0-9][0-9],xplt.*," %LOG_DIR%\*.log') do #echo %%L,%%M,%%N:%%O:%%P,%%Q,%%R,
`

REM
#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir"
FOR /f "tokens=2-8delims=:, " %%a IN ('findstr /l /i /c:", XPLT" "%sourcedir%\*.log"') DO (
ECHO %%~nxa,%%b,%%c:%%d:%%e,%%f,%%g
)
GOTO :eof
redirect to your .csv as you will...

Answer 3

#echo off
setlocal enableextensions disabledelayedexpansion
:: configuration
set "logFolder=%cd%"
set "logFiles=*.log"
set "maxFileAge=30"
set "computerName=XPLT"
set "outputFile=CitrixLogs.csv"
:: adjust commands to execute according to configuration
set "ageFilter=robocopy "%logFolder%" "%logFolder%" "%logFiles%" /l /is /njh /njs /nc /ns /ndl /maxage:%maxFileAge%"
set "contentFilter=findstr /f:/ /i /r /c:"^^[^^,]*, [^^,]*, %computerName%" "
:: Generate output file
( echo(EID,Date,PCName,IPAdd
for /f "usebackq tokens=2,* delims=:" %%a in (
`cmd /q /c "for /f tokens^=* %%a in ('%ageFilter%') do echo(%%a" ^| %contentFilter% `
) do for /f "tokens=1,3,4 delims=," %%c in ("%%b") do echo(%%~nxa,%%c,%%d,%%e
) > "%outputFile%"
endlocal
This will use robocopy (or you can change it with forfiles) to search for files with a max age of 30 days in the indicated folder. Files will not be copied (/l) but the list will be echoed (the rest of the switch configure the output). This list of files is piped into findstr (/f:/) indicating where to search for the lines that match the indicated condition. This will generate an output with each line in the input file matching the condition, prefixed with the name (full name) of the file. This line is then splitted to output only the required fields.
