Unzip to a specific level

Hello gurus, this should be simple but I cant seem to figure this out. Please assist.

I have several thousand zip files in a directory

A.ZIP
B.ZIP
.
.
..
Z.ZIP

All these zipped files have a single subdirectory at level1 and then other files and folders under the subdirectory.

Example

A.ZIP
------Subfolder12
------------FilesandSubSubFolders

If I unzip A.ZIP, the unzipped folder is called Subfolder12, which I want to be named as A

If I use

unzip A.zip

The result is

Subfolder12
--------FilesandSubfolders

If I do

unzip A.zip -d A

the result is

A
-----Subfolder12
-------------FilesandSubfolders

What I want is

A
------FilesandSubfolders

i`m trying to do this in a loop.

for file in *.zip
do
unzip $file -d ${file%.zip}
done

Perhaps

for f in *.zip; do
    if [[ -e "$f" ]]; then
        unzip "$f" && mv -v "Subfolder12" "${f%.zip}"
    fi
done

Untested.

The subfolder is not necessarily called subfolder12, its any random name at level1. So every zip will have a different name for the subfolder at level 1.

In that case we have to find out what's that first directory's name. I am using unzip to tell me.

for f in *.zip; do
    if [[ -e "$f" ]]; then
        unzip "$f"
        firstdir=$(unzip -qql "$f" | head -1)
        mv -v "${firstdir##* }" "${f%.zip}"
    fi
done

If you have a tar utility that supports --strip-componets:

for f in *.zip; do
    if [[ -e "$f" ]]; then
        mkdir "${f%.zip}" && tar xvzf "$f" --strip-components=1 -C "${f%.zip}"
    fi
done

Again, all these are edited on the fly. Untested.
