I've got a folder that has 68 archives in it ranging from .rar, .ace, & .zip.

I want to extract all of these files using their folder name as the first directory ("Extract here")

If I use file-roller it halts at the first error, there doesn't appear to be an "ignore error" flag for file roller.

If I use 7zip it dumps everything into the current folder and doesn't use clean folders

How can I extract everything into separate folders without spilling everything into the current directory?

Answer 1

for i in *; do mkdir "$i.extracted"; (cd "$i.extracted" && 7z x "../$i") || echo "Error with $i"; done

Answer 2

I'm not aware of any direct solution but with a little bash loop you can do it in a terminal (if, as your question seems to suggest, 7zip is able to do everything you want except for extracting into a folder based on the filename). Try (in the directory with the archives):

for FILE in *.*; do DIR=${FILE%.*}; mkdir $DIR && 7z x -o$DIR $FILE ; done

The ${FILE%.*} extracts the filename without the extension.

Answer 3

A little shell scripting might come to the rescue.

#! /bin/bash

for archive in "$@"; do (
    archive_dir="$(cd $(dirname "$archive"); pwd -P)"
    archive_name="$(basename "$archive")"
    # make a directory by appending `.d` to the archive file name
    name="${archive_name}.d"
    mkdir -p "$name"
    cd "$name"
    # extract contents with full path, 
    # replace 'x' with 'e' to extract into $name directory
    7z x "${archive_dir}/${archive_name}"
); done

Paste the above into a file extract.sh (in the directory where you want to extract files) and then make it executable:

chmod +x ./extract.sh

The script creates a directory for each archive given on the command line by appending .d to its file name (e.g., for an archive stuff.zip it will create directory stuff.zip.d), and then extracts files from the archive into it.

You can invoke it in a terminal like this (use wildcards to extract multiple archives in one go):

./extract.sh stuff.zip stuff2.rar

Disclaimer: untested, so try it out with one or two sample archives before making the big run.
