Batch script to extract .7z files

[Dwight Army of Champions]

Suppose I have a folder that contains several .7z files. I want to
write a batch script that will do the following:

for each file abc.7z in the current directory:
create a new folder abc in current directory if it does not exist
extract all files in abc.7z and store in folder abc
for each file to be extracted
if any of the extracted files begin with string abc, then
remove abc from filename
end if
end for
end for

How do I do this?

Use a for in do loop for this part:

@echo off
for /f "delims=" %%a in ('dir "*.7z" /b') do (
echo "%%a"
rem the rest of your code goes here.
)

> create a new folder abc in current directory if it does not exist

This will create the folder regardless and send any harmless error message to nul so it isn't displayed.

md "%%a" 2>nul


You haven't specified what you need to do if the folder already exists.

> extract all files in abc.7z and store in folder abc

Use the 7z command line tool to do this.

This is an unusual requirement.

Will it be ok to process the entire tree?
What happens if the 7z files have embedded subdirectories? Would you want to remove abc from the start of every file in every folder?
What should happen if there is filename collision with an existing filename? (EG abcten.txt and ten.txt)

There's a start. See what you can construct and feel free to post further questions.

tries to create a directory with the same name as the .7z file (which
produces an error since a file with that name already exists). I want
to create a directory whose name is just the root of the filename
(everything up to but not including the extension)

I think that should have been

md "%%~na" 2>nul

Thanks, that worked well.

Now on to the next part: I want to cd into the new directory and
remove from each filename the name of the directory. For example, in
directory abc, I have a lot of
extracted file like abc (EN),txt, abc (FR).txt, abc (DE).txt, etc. I
just want to rename each file to (EN).txt, (FR).txt, (DE).txt, etc.
Remove the directory name from the extracted filename. How do I do
that? I've got the directory name as %%~na, so how do I remove that
from each filename?

Theoretically,

for %%a in (*.7z) do (

7z x "%%a" -o"%%~na"

pushd "%%~na"
for /f "tokens=1*delims= " %%i in ( ' dir /b /a-d *.* ' ) do (
if /i "%%i"=="%%~na" ECHO ren "%%i %%j" "%%j"
)
popd
)

where the ECHO will siply show the rename on the screen. If you deem it
correct, remove the ECHO keyword to execute the rename.

- Assuming that the files ou want to rename have names following the pattern
"abc something" as indicated.
- No attempt is made here to handle the situation where the new filename
already exists.

Unfortunately, that only worked for folders that don't have spaces in
their names. Forexample, for a file "Of Mice and Men (EN).7z" in a
folder "Of Mice and Men", the .7z file only gets renamed to "Mice and
Men (EN).7z"

How about this:

Foreach file in the current directory
if the entire text of the parent directory is in the current file
remove the text of the parent directory from the current file
else
do nothing
end if
end for

Is this possible?

You need to be very precise in your specification.

...
for /f "tokens=1*delims=(" %%i in ( ' dir /b /a-d *.* ' ) do (
if /i "%%i"=="%%~a" ECHO REN "%%i(%%j" "(%%j"
...

may work for you. Without knowing what you expect to happen - like

rename "Of Mice and Men (EN).7z" in a folder "Of Mice and Men" to "(EN).7z"

for instance; saying what it does and complaining that it's wrong doesn't
tell us what is right. Your original question did not make it clear whether
the crucial factor was the space preceding the parenthesis or the
parenthesis itself.

You revised specification does not tell us whether the file

"Supplemental Of Mice and Men (EN).7z" should be renamed for instance, and
if so to what. Implicitly, it would need to be changed to "Supplemental
(EN).7z"

Is the critical issue a match precisely on [begins-directoryname]something
to be renamed to something, or is the string-in-parenthesis-pair (critical,
unique, fixed-length, irrelevant?)

The above should work if the filename is precisely

directoryname(something

to be renamed to

(something

How would a filename

Of (Mice and) Men (EN).7z

in directoryname

Of (Mice and) Men

be handled for instance?

Try this and see if the output is what you want. If the output looks
correct, remove the ECHO to enable the batch.

@echo off
call :process "Of Mice and Men" "Of Mice and Men (EN).txt"
goto :eof

for %%a in (*.7z) do (
7z x "%%a" -o"%%~na"
pushd "%%~na"

for /f "delims=" %%i in ( ' dir /b /a-d "%%~na*.*" ' ) do (
call :process "%%~na" "%%~i"
)
popd
)
goto :eof
:process
setlocal enabledelayedexpansion
set "file=%~2"
set "file=!file:%~1=!"
if "%file:~0,1%" equ " " set "file=%file:~1%"
ECHO ren %2 "%file%"
