How to extract .zip without zip folder name - bash

I want to download a .zip kernel from github, give it a name kernel.zip and extract its contents inside kernel folder. I did this:
mkdir kernel
wget -O kernel.zip https://github.com/MiCode/Xiaomi_Kernel_OpenSource/archive/surya-q-oss.zip -d kernel
#-o for overwrite all and -d for specifying where to put the files
unzip -o kernel.zip -d kernel
But it extracts to kernel/Xiaomi_Kernel_OpenSource-surya-q-oss/ instead of kernel.
Adding -j as said here: https://unix.stackexchange.com/questions/72838/unzip-file-contents-but-without-creating-archive-folder does not help, it simply places all files in the same place.
This solution: https://askubuntu.com/a/1088207 involves knowing the archive name (Xiaomi_Kernel_OpenSource-surya-q-oss for this case), which I don't know

Extracting XIP file on linux ends with missing files

I tried extract the Xcode XIP file download from here, following the instructions in this tutorial: https://gist.github.com/phracker/1944ce190e01963c550566b749bd2b54
Unpacking XIP files on Linux:
Install xar from https://mackyle.github.io/xar/
Install pbzx from https://github.com/NiklasRosenstein/pbzx (use gcc -llzma -lxar -I /usr/local/include pbzx.c -o pbzx and copy the binary into your PATH)
use xar -xf XIP_FILE -C /path/to/extract/to
Change to the directory where you extracted the file.
Use pbzx -n Content | cpio -i to extract the contents.
But the result seems to be missing some files. For example, when I go to:
Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/System/Library/Frameworks/
every single on the folders here have only subfolders inside, with no file (I think should be some header files inside the Header subfolder, which is empty, and a *.swiftmodule file inside the subfolder Modules- ther eis only an empty folder with this name)
What I am missing here? The instructions above are missing some step?

Extract only files with specific extension via bash

For a first time I need to create an .sh for do something. My aim is to unzip a lot of zip folders, so I've wrote the script below:
for zipfiles in /downloads/*.zip; do unzip $zipfiles; done
I can unzip all but I noticed that there are some files with the same name and typing y I can ultimate the process.
There is a way to extract only files with a specific extension, like .docx, instead of the entire zip folder? I'm absolutely sure that there aren't .docx with the same name.
You can specify a pattern:
for zipfiles in /downloads/*.zip; do unzip "$zipfiles" '*.docx'; done
Tested to work with UnZip 6.00.
You can also specify the -x option to exclude.
try this one, it can be useful for your purpose.
for zipfiles in /downloads/*.zip; do unzip -xo "$zipfiles" '*.docx' ; done
by this option overwrite files WITHOUT prompting.

zip created using -jr flags unzipped differently on macOS when double clicking vs running unzip

I am zipping the .xctest file from Plugins folder inside the .app target generated by building my app. I have a build phase script that runs last in my test target to copy this file over. I use the following script to do the zipping:
XCTEST_FILE=${TARGET_BUILD_DIR}/${TARGET_NAME}.xctest
XCTEST_ZIP=${TARGET_BUILD_DIR}/../../${TARGET_NAME}.xctest.zip
zip -jr ${XCTEST_ZIP} ${XCTEST_FILE}
This gives me TestTarget.xctest.zip file. But it unzips differently based on these 2 methods,
unzip TestTarget.xctest.zip
-TestTarget
-CodeResources
-Info.plist
Double clicking TestTarget.xctest.zip in finder
-TestTarget.xctest
--TestTarget
--CodeResources
--Info.plist
Why is unzip going to the innermost node and extracting all the files? I want the unzip command to give me the .xctest directory. I tried renaming the zip file to TestTarget.zip and it still behaves similarly.
I was initially zipping using zip -r ${XCTEST_ZIP} ${XCTEST_FILE}, but the problem with this was it would retain the entire folder structure from root (\) when I double clicked to unzip the file. A post recommend using the -j flag instead of -r. But just -j led to no zip file being generated. Another comment recommend -jr which created a zip that generated output I expected when double clicking it. But I guess the unzip command does stuff differently.
Similar Question: MacOs zip file - different result when double click and running unzip command
The cause for error here was very different,
The problem was when the file was created. It was not related to MacOs issue but with certain path length known issue in windows
Based on How to zip folder without full path, I had to update my script to first cd into the TARGET_BUILD_DIR before generating the zip. I also had to remove the -j flag so the local folder structure was retained on running unzip.
cd ${TARGET_BUILD_DIR}
XCTEST_FILE=./${TARGET_NAME}.xctest
XCTEST_ZIP=../../${TARGET_NAME}.xctest.zip
zip -r ${XCTEST_ZIP} ${XCTEST_FILE}

make rebuild target depending on zip file

Why make rebuilds the target (I suppose) if the dependency is a binary file?
To reproduce:
create (and enter it) a new empty directory
download the GameLift SDK (it is just an example: the Makefile content on this question is an example with this file)
create a simple Makefile with the content below
issue more times the make command
all: GameLift_12_22_2020/GameLift-SDK-Release-4.0.2/GameLift-Cpp-ServerSDK-3.4.1/CMakeLists.txt
GameLift_12_22_2020/GameLift-SDK-Release-4.0.2/GameLift-Cpp-ServerSDK-3.4.1/CMakeLists.txt: GameLift_12_22_2020.zip
unzip -oq GameLift_12_22_2020.zip
I would have expected to see the unzip command to be executed only first time I issue the make command, but it continue to be executed in next make runs... why?
There are two possibilities, we cannot know which is the case with the information you've provided.
The first is that the file GameLift_12_22_2020/GameLift-SDK-Release-4.0.2/GameLift-Cpp-ServerSDK-3.4.1/CMakeLists.txt is not present in the zip file, so the second time make runs it looks to see if that file exists and it doesn't, so it re-runs the rule. If, in the same directory you run make, you use ls GameLift_12_22_2020/GameLift-SDK-Release-4.0.2/GameLift-Cpp-ServerSDK-3.4.1/CMakeLists.txt (after the unzip runs) and you get "file not found" or similar, this is your problem.
If that's not it, then the problem is that the timestamp of the file in the zip file is older than the zip file itself, and when unzip unpacks the file it sets the timestamp to this older time.
So when make goes to build it finds the CMakeLists.txt file but the modification time is older than the zip file, so make unpacks the zip file again to try to update it.
You can use ls -l to see the modification time on that file. If this is the case you should touch the file when you unpack it, so it's newer:
GameLift_12_22_2020/GameLift-SDK-Release-4.0.2/GameLift-Cpp-ServerSDK-3.4.1/CMakeLists.txt: GameLift_12_22_2020.zip
unzip -oq GameLift_12_22_2020.zip
touch $#

Mac zip compress without __MACOSX folder?

When I compress files with the built in zip compressor in Mac OSX, it causes an extra folder titled "__MACOSX" to be created in the extracted zip.
Can I adjust my settings to keep this folder from being created or do I need to purchase a third party compression tool?
UPDATE: I just found a freeware app for OSX that solves my problem: "YemuZip"
UPDATE 2: YemuZip is no longer freeware.
Can be fixed after the fact by zip -d filename.zip __MACOSX/\*
And, to also delete .DS_Store files: zip -d filename.zip \*/.DS_Store
When I had this problem I've done it from command line:
zip file.zip uncompressed
EDIT, after many downvotes: I was using this option for some time ago and I don't know where I learnt it, so I can't give you a better explanation. Chris Johnson's answer is correct, but I won't delete mine. As one comment says, it's more accurate to what OP is asking, as it compress without those files, instead of removing them from a compressed file. I find it easier to remember, too.
Inside the folder you want to be compressed, in terminal:
zip -r -X Archive.zip *
Where -X means: Exclude those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files
source
Note: Will only work for the folder and subsequent folder tree you are in and has to have the * wildcard.
This command did it for me:
zip -r Target.zip Source -x "*.DS_Store"
Target.zip is the zip file to create. Source is the source file/folder to zip up. The -x parameter specifies the file/folder to exclude.
If the above doesn't work for whatever reason, try this instead:
zip -r Target.zip Source -x "*.DS_Store" -x "__MACOSX"
I'm using this Automator Shell Script to fix it after.
It's showing up as contextual menu item (right clicking on any file showing up in Finder).
while read -r p; do
zip -d "$p" __MACOSX/\* || true
zip -d "$p" \*/.DS_Store || true
done
Create a new Service with Automator
Select "Files and Folders" in "Finder"
Add a "Shell Script Action"
zip -r "$destFileName.zip" "$srcFileName" -x "*/\__MACOSX" -x "*/\.*"
-x "*/\__MACOSX": ignore __MACOSX as you mention.
-x "*/\.*": ignore any hidden file, such as .DS_Store .
Quote the variable to avoid file if it's named with SPACE.
Also, you can build Automator Service to make it easily to use in Finder.
Check link below to see detail if you need.
Github
The unwanted folders can be also be deleted by the following way:
zip -d filename.zip "__MACOSX*"
Works best for me
The zip command line utility never creates a __MACOSX directory, so you can just run a command like this:
zip directory.zip -x \*.DS_Store -r directory
In the output below, a.zip which I created with the zip command line utility does not contain a __MACOSX directory, but a 2.zip which I created from Finder does.
$ touch a
$ xattr -w somekey somevalue a
$ zip a.zip a
adding: a (stored 0%)
$ unzip -l a.zip
Archive: a.zip
Length Date Time Name
-------- ---- ---- ----
0 01-02-16 20:29 a
-------- -------
0 1 file
$ unzip -l a\ 2.zip # I created `a 2.zip` from Finder before this
Archive: a 2.zip
Length Date Time Name
-------- ---- ---- ----
0 01-02-16 20:29 a
0 01-02-16 20:31 __MACOSX/

-------- -------
149 3 files
-x .DS_Store does not exclude .DS_Store files inside directories but -x \*.DS_Store does.
The top level file of a zip archive with multiple files should usually be a single directory, because if it is not, some unarchiving utilites (like unzip and 7z, but not Archive Utility, The Unarchiver, unar, or dtrx) do not create a containing directory for the files when the archive is extracted, which often makes the files difficult to find, and if multiple archives like that are extracted at the same time, it can be difficult to tell which files belong to which archive.
Archive Utility only creates a __MACOSX directory when you create an archive where at least one file contains metadata such as extended attributes, file flags, or a resource fork. The __MACOSX directory contains AppleDouble files whose filename starts with ._ that are used to store OS X-specific metadata. The zip command line utility discards metadata such as extended attributes, file flags, and resource forks, which also means that metadata such as tags is lost, and that aliases stop working, because the information in an alias file is stored in a resource fork.
Normally you can just discard the OS X-specific metadata, but to see what metadata files contain, you can use xattr -l. xattr also includes resource forks and file flags, because even though they are not actually stored as extended attributes, they can be accessed through the extended attributes interface. Both Archive Utility and the zip command line utility discard ACLs.
You can't.
But what you can do is delete those unwanted folders after zipping. Command line zip takes different arguments where one, the -d, is for deleting contents based on a regex. So you can use it like this:
zip -d filename.zip __MACOSX/\*
Cleanup .zip from .DS_Store and __MACOSX, including subfolders:
zip -d archive.zip '__MACOSX/*' '*/__MACOSX/*' .DS_Store '*/.DS_Store'
Walkthrough:
Create .zip as usual by right-clicking on the file (or folder) and selecting "Compress ..."
Open Terminal app (search Terminal in Spotlight search)
Type zip in the Terminal (but don't hit enter)
Drag .zip to the Terminal so it converts to the path
Copy paste -d '__MACOSX/*' '*/__MACOSX/*' .DS_Store '*/.DS_Store'
Hit enter
Use zipinfo archive.zip to list files inside, to check (optional)
I have a better solution after read all of the existed answers. Everything could done by a workflow in a single right click.
NO additional software, NO complicated command line stuffs and NO shell tricks.
The automator workflow:
Input: files or folders from any application.
Step 1: Create Archive, the system builtin with default parameters.
Step 2: Run Shell command, with input as parameters. Copy command below.
zip -d "$#" "__MACOSX/*" || true
zip -d "$#" "*/.DS_Store" || true
Save it and we are done! Just right click folder or bulk of files and choose workflow from services menu. Archive with no metadata will be created alongside.
IMAGE UPDATE: I chose "Quick Action" when creating a new workflow - here’s an English version of the screenshot:
do not zip any hidden file:
zip newzipname filename.any -x "\.*"
with this question, it should be like:
zip newzipname filename.any -x "\__MACOSX"
It must be said, though, zip command runs in terminal just compressing the file, it does not compress any others. So do this the result is the same:
zip newzipname filename.any
Keka does this. Just drag your directory over the app screen.
Do you mean the zip command-line tool or the Finder's Compress command?
For zip, you can try the --data-fork option. If that doesn't do it, you might try --no-extra, although that seems to ignore other file metadata that might be valuable, like uid/gid and file times.
For the Finder's Compress command, I don't believe there are any options to control its behavior. It's for the simple case.
The other tool, and maybe the one that the Finder actually uses under the hood, is ditto. With the -c -k options, it creates zip archives. With this tool, you can experiment with --norsrc, --noextattr, --noqtn, --noacl and/or simply leave off the --sequesterRsrc option (which, according to the man page, may be responsible for the __MACOSX subdirectory). Although, perhaps the absence of --sequesterRsrc simply means to use AppleDouble format, which would create ._ files all over the place instead of one __MACOSX directory.
This is how i avoid the __MACOSX directory when compress files with tar command:
$ cd dir-you-want-to-archive
$ find . | xargs xattr -l # <- list all files with special xattr attributes
...
./conf/clamav: com.apple.quarantine: 0083;5a9018b1;Safari;9DCAFF33-C7F5-4848-9A87-5E061E5E2D55
./conf/global: com.apple.quarantine: 0083;5a9018b1;Safari;9DCAFF33-C7F5-4848-9A87-5E061E5E2D55
./conf/web_server: com.apple.quarantine: 0083;5a9018b1;Safari;9DCAFF33-C7F5-4848-9A87-5E061E5E2D55
Delete the attribute first:
find . | xargs xattr -d com.apple.quarantine
Run find . | xargs xattr -l again, make sure no any file has the xattr attribute. then you're good to go:
tar cjvf file.tar.bz2 dir
Another shell script that could be used with the Automator tool (see also benedikt's answer on how to create the script) is:
while read -r f; do
d="$(dirname "$f")"
n="$(basename "$f")"
cd "$d"
zip "$n.zip" -x \*.DS_Store -r "$n"
done
The difference here is that this code directly compresses selected folders without macOS specific files (and not first compressing and afterwards deleting).
