parse csv to make more readable - csv

Question

I am using PsInfo from sysinternals to return drive information in the form of a csv.
When I run this command.
psinfo -c -d volume
I get the following output.
PCName,,C:,Fixed,NTFS,,930.97 GB,705.81 GB,75.8%,D:,CD-ROM,,,,,0.0%,G:,Fixed,NTFS,My Book,1862.98 GB,889.71 GB,47.8%
My goal here is to parse that output to achieve this format:
PCNAME,,
,,C:,Fixed,NTFS,,930.97 GB,705.81 GB,75.8%
,,G:,Fixed,NTFS,My Book,1862.98 GB,889.71 GB,47.8%
So when the output is read by a spreadsheet viewer it appears readable and organized.
I've tried using regex to match the drive letter bit I don't know how to correctly capture the output.
Edit: (forgot to actually post my code...)
This is what I have so far.
ECHO OFF
For /f "tokens=1*" %%x in ('net view ^| find "\\"') do (psinfo %%x filter -d -c >> out.csv & echo. >> out.csv)
::used to remove blanmk lines from output
#jrepl "^[ \t]*(.*?)[ \t]*$" "$1?$1:false" /jmatch /f out.csv /o -
pause

Answer 1

#ECHO OFF
SETLOCAL enabledelayedexpansion
FOR /f "delims=" %%a IN ('psinfo -c -d volume') DO SET "var=%%a"
SET "var2=!var:%%=\!"
SET "retained="
:again
REM FOR /f "tokens=delims==:" %%a IN () DO
FOR /f "tokens=1*delims=:" %%a IN ("%var2%") DO (
CALL :FORMAT "%%a"
SET "var2=%%b"
IF NOT "%%b"=="" GOTO again
)
GOTO :EOF
:FORMAT
SET "data=%~1"
IF "%data:~-1%"=="\" (SET "data=%retained%:%data%") ELSE (SET "data=%retained%:%data:~,-2%")
IF DEFINED retained (
ECHO ,,!data:\=%%!
) ELSE (
ECHO %data:~1%,
)
SET "retained=%~1"
SET retained=%retained:~-1%
GOTO :eof
substitutes \ for % for ease of processing.

This worked for me. Given this example you should be able to play around with the format of the output you desire.
#echo off
FOR /F "tokens=1* delims=," %%G IN ('psinfo -c -d volume') DO (
SET "pcname=%%G"
SET "driveinfo=%%H"
)
set driveinfo="%driveinfo:,=","%"
:LOOP
FOR /F "tokens=1-7* delims=," %%G IN ("%driveinfo%") DO (
echo "%pcname%",%%G,%%H,%%I,%%J,%%K,%%L,%%M
SET "driveinfo=%%N"
)
IF DEFINED driveinfo GOTO LOOP
Output
"COCO","C:","Fixed","NTFS","","930.97 GB","705.81 GB","75.8%"
"COCO","G:","Fixed","NTFS","My Book","1862.98 GB","889.71 GB","47.8%"
And here is the code changed to replicate your exact needed Output.
#echo off
FOR /F "tokens=1* delims=," %%G IN ('psinfo -c -d volume') DO (
SET "pcname=%%G"
SET "driveinfo=%%H"
)
set driveinfo="%driveinfo:,=","%"
echo %pcname%,,
:LOOP
FOR /F "tokens=1-7* delims=," %%G IN ("%driveinfo%") DO (
echo ,,%%~G,%%~H,%%~I,%%~J,%%~K,%%~L,%%~M
SET "driveinfo=%%N"
)
IF DEFINED driveinfo GOTO LOOP
And here is doing it in a couple of less lines.
#echo off
setlocal enabledelayedexpansion
FOR /F "tokens=1* delims=," %%G IN ('psinfo -c -d volume') DO (
echo %%G,,
SET "driveinfo=%%H"
)
set "drive2=echo ,,!driveinfo:%%=%%&echo,,!"
%drive2:~0,-1%

You can get the same information with Powershell, eg with the Get-Volume command. This returns, everything except the ration eg:
DriveLetter FileSystemLabel FileSystem DriveType HealthStatus OperationalStatus SizeRemaining Size
----------- --------------- ---------- --------- ------------ ----------------- ------------- ----
D CD-ROM Healthy Unknown 0 B 0 B
C Win7 NTFS Fixed Healthy OK 43.59 GB 238.03 GB
H Projects NTFS Fixed Healthy OK 96.73 GB 375.24 GB
Get-Volume returns volume information objects. The shell just displays the most common ones.
You can select only the properties you want, and add more columns with the select command:
Get-Volume | where {$_.DriveType -ne 'CD-ROM'}
| select DriveLetter, FileSystemLabel,FileSystem,SizeRemaining, Size,
#{Name="Ratio";Expression={"{0:P}" -f ($_.SizeRemaining/$_.Size)}}
|Format-Table
DriveLetter FileSystemLabel FileSystem SizeRemaining Size Ratio
----------- --------------- ---------- ------------- ---- -----
C Win7 NTFS 46793633792 255584587776 18,31%
H Projects NTFS 103853056000 402911129600 25,78%
I'm cheating a bit here, by filtering out the CD ROM with where
If the results are too long to fit in the window, Powershell displays them as a list of name/values. The final Format-Table is used to force Powershell to format the results as a table
I can store the table to a file with a normal redirection :
Get-Volume | where {$_.DriveType -ne 'CD-ROM'}
| select DriveLetter, FileSystemLabel,FileSystem,SizeRemaining, Size,
#{Name="Rate";Expression={"{0:P}" -f ($_.SizeRemaining/$_.Size)}}
|Format-Table > somefile.txt
or I can export the results to a real CSV with Export-CSV
Get-Volume | where {$_.DriveType -ne 'CD-ROM'}
| select DriveLetter, FileSystemLabel,FileSystem,SizeRemaining, Size,
#{Name="Rate";Expression={"{0:P}" -f ($_.SizeRemaining/$_.Size)}}
| Export-CSV somefile.csv

The following code snippet reformats the output of psinfo -c -d volume as you wish. Since it seems that you want it filtered by drive type (Fixed) according to your sample data, I implemented such a feature; to not filter anything, simply change line set "FILTER=Fixed" to set "FILTER=":
#echo off
setlocal EnableExtensions DisableDelayedExpansion
rem // Define constants here:
set "FILTER=Fixed"
(set LF=^
%= empty line =%
)
for /F "tokens=1,* delims=, eol=," %%K in ('psinfo -c -d volume') do (
echo(%%K,,
set "LINE=%%L"
setlocal EnableDelayedExpansion
set ^"LINE=!LINE:%%,=%%^%LF%%LF%!^"
for /F "delims= eol=," %%E in ("!LINE!") do (
endlocal
if defined FILTER (
for /F "tokens=2 delims=, eol=," %%F in ("%%E") do (
if "%%F"=="%FILTER%" (
echo(,,%%E
)
)
) else (
echo(,,%%E
)
setlocal EnableDelayedExpansion
)
endlocal
)
endlocal
exit /B
