I want to recompress tar.gz files to 7z (the contents of the tar, not the tar itself). As there are no real solutions I could find (yet - there's PeaZIP but there first all files are uncompressed, then re-compressed and only then are files deleted), I thought I'd write a simple bat/cmd file.
The file should process all tar.gz files in the folder of the batch file (no subfolders needed). Unpack the tar and then save the tar-contents into a folder with the base-name of the file. 7zip can do that in one step, something like (I still would need to provide the extract folder): 7z x %1 -so | 7z x -si -ttar.
All my files have the following name YYYYMMDD.tar.gz, so the base-name is simply getting the left 8 characters (the script would struggle with the double extension anyway).
I can loop the files like this: for %%i in (*.tar.gz) do
And then I need to add the compress step of course. I tried for a while but I get stuck with %% and ~ all the time :(.
Anyone who can give me a kick start here please?

Following that link, have you solved your problem?
The syntax of 7Zip can be somewhat idiosyncratic!

Re: Trouble with batch file
I used 'tar' (available in the latest versions of Win10) tot unpack a tar.gz in one time:
This runs in a CMD file (BNam is the target folder, %%F is the tar.gz file)
Then later in my CMD file I create the 7z file
Code: Select all
tar -xzf "%%F" -C !BNam!
Then later in my CMD file I create the 7z file
Code: Select all
..\7za a -t7z "..\!BNam!.7z" * -mx=9
