Order and move files into directories based on some filenames pattern - powershell

Question

To move files into folders I use this script
#echo off
setlocal EnableExtensions DisableDelayedExpansion
rem // Define constants here:
set "SPLITCHAR=-" & rem // (a single character to split the file names)
set "SEARCHSTR=_" & rem // (a certain string to be replaced by another)
set "REPLACSTR= " & rem // (a string to replace all found search strings)
set "OVERWRITE=" & rem // (set to non-empty value to force overwriting)
rem // Get file location and pattern from command line arguments:
set "LOCATION=%~1" & rem // (directory to move the processed files into)
set "PATTERNS=%~2" & rem // (file pattern; match all files if empty)
rem /* Prepare overwrite flag (if defined, set to character forbidden
rem in file names; this affects later check for file existence): */
if defined OVERWRITE set "OVERWRITE=|"
rem // Continue only if target location is given:
if defined LOCATION (
rem // Create target location (surpress error if it already exists):
2> nul md "%LOCATION%"
rem /* Loop through all files matching the given pattern
rem in the current working directory: */
for /F "eol=| delims=" %%F in ('dir /B "%PATTERNS%"') do (
rem // Process each file in a sub-routine:
call :PROCESS "%%F" "%LOCATION%" "%SPLITCHAR%" "%SEARCHSTR%" "%REPLACSTR%"
)
)
endlocal
exit /B
:PROCESS
rem // Retrieve first argument of sub-routine:
set "FILE=%~1"
rem // Split name at (first) split character and get portion in front:
for /F "delims=%~3" %%E in ("%~1") do (
rem // Append a split character to partial name:
set "FOLDER=%%E%~3"
)
setlocal EnableDelayedExpansion
rem // Right-trim partial name:
if not "%~4"=="" set "FOLDER=!FOLDER:%~4%~3=!"
set "FOLDER=!FOLDER:%~3=!"
rem /* Check whether partial name is not empty
rem (could happen if name began with split character): */
if defined FOLDER (
rem // Replace every search string with another:
if not "%~4"=="" set "FOLDER=!FOLDER:%~4=%~5!"
rem // Create sub-directory (surpress error if it already exists):
2> nul md "%~2\!FOLDER!"
rem /* Check if target file already exists; if overwrite flag is
rem set (to an invalid character), the target cannot exist: */
if not exist "%~2\!FOLDER!\!FILE!%OVERWRITE%" (
rem // Move file finally (surpress `1 file(s) moved.` message):
1> nul move /Y "!FILE!" "%~2\!FOLDER!"
)
)
endlocal
exit /B
To use script I must
1- open cmd
2- to execute batch i have to
cd C:\Users\Administrator\Desktop\T\
"C:\Users\Administrator\Desktop\T\build-folder-hierarchy.bat" "C:\Users\Administrator\Desktop\T\" "*.pdf"
But problem what is ?
For each .pdf file batch creates a relative folder but I don't want it creates folders in that way. Look http://i.imgur.com/TVhQyzv.png
aaaa aaaa S02 [folder]
aaaa aaaa S02e01.pdf [folder]
aaaa aaaa S02e02.pdf [folder]
aaa.aaaa.aaa.aa.aaaaa.S02 [folder]
What I want instead ?
├─aaaa aaaa S02 [folder]
│ ├─aaaa aaaa S02e01.pdf[file]
│ ├─aaaa aaaa S02e02.pdf [file]
└─ ....
├─aaa.aaaa.aaa.aa.aaaaa.S02 [folder]
│ └─aaa.aaaa.aa.aa.aaaaa.S02E13.pdf [file]
:
Just an example name to understand how .pdf files name are formatted
aaaaaaaaa aa aaaaa S01e12 720p Repack.pdf
aaa aaaaaaaaa S01e05 Versione 720p.pdf
aaa aaaaaaaa S01e05 Versione 1080p.pdf
aaa aaaa s2e06.pdf
aaa aaaa S03e12.pdf
aaa.aaaa.aaa.on.Earth.S02E13.pdf
aaa.aaaa.aaaa.S02E01.HDTV.x264.SUB.ITA.pdf
Usually pdf files name are formatted in this way [pattern]
s01
s01e1
s1
s1e1
s1e01
s1e01-10
character, like the e and s are almost always present within these patterns name
general form should be
sxx
sxxex
sx
sxex
sxexx
sxexx-xx
X is a number, case for letter s and e is irrilevant
Powershell solution is well accepted for answer.

Answer 1

Your question is confusing. You have not described the format of the file names, but just show some examples and using examples instead of specifications may be misunderstood. Post code wrote for other problem that don't work on this one is certainly not useful. You did not showed an example of the input and wanted output using real file names, so it is possible that a solution based on the example data will not work on real data.
EDIT: New specification added. Both specifications and program code have been modified accordingly to a request given in comments.
Below there are the specifications of this problem as I understand they:
"Given a series of *.pdf files with this format:
any string hereS##Eany string here.pdf
/ | ^-- "E" letter
"S" letter digit
extract the string that ends before the "E" after the "S-digit" delimiter and move the file to a folder with such a name, "S" and "E" letters are not case sensitive. Ignore files that have not the previous format."
This code solve the problem based on such specifications:
#echo off
setlocal EnableDelayedExpansion
rem Change current directory to the one where this .bat file is located
cd "%~P0"
set "digits=0123456789"
rem Process all *.pdf files
for %%f in (*.pdf) do (
rem Get the folder name of this file
call :getFolder "%%f"
rem If this file have a properly formatted name: "headS##Etail"
if defined folder (
rem Move the file to such folder
if not exist "!folder!" md "!folder!"
move "%%f" "!folder!"
)
)
goto :EOF
:getFolder file
set "folder="
set "file=%~1"
set "head="
set "tail=%file%"
:next
for /F "delims=%digits%" %%a in ("%tail%") do set "head=%head%%%a"
set "tail=!file:*%head%=!"
if not defined tail exit /B
if /I "%head:~-1%" equ "S" goto found
:digit
if "!digits:%tail:~0,1%=!" equ "%digits%" goto noDigit
set "head=%head%%tail:~0,1%"
set "tail=%tail:~1%"
goto digit
:noDigit
goto next
:found
for /F "delims=Ee" %%a in ("%tail%") do set "folder=%head%%%a"
exit /B
To use this Batch file, place it on the same folder where the original files are located and execute it without parameters; you may also execute it via a double-click in the explorer. Example session:

This code would be much simpler if the file name before the "S" delimiter can not have digits. This solution assumes that there are not exclamation-marks ! in the file names.

Answer 2

The easiest way to get the last instance of a regex substring is to break the string into chunks and process the chunks in reverse order.
