Unzip files in phone from ADB terminal

I am trying to unzip files in my android (11) phone with ADB from the terminal (Ubuntu 20.04). I need to run a script from my Ubuntu laptop to unzip files on my phone.
I have already tried Busybox from this suggestion. With this app, I can unzip files after accessing the shell. I mean -
$ adb shell
a60q:/ $ cd /sdcard/
a60q:/sdcard $ unzip data.zip
Archive: data.zip
inflating: Screenshot from 2020-11-30 16-45-46 (7th copy).png
inflating: Screenshot from 2020-11-30 16-45-46 (10th copy).png
But when I try to use the direct command, it shows an error.
$ adb shell unzip /sdcard/data.zip
unzip: couldn't create file Screenshot from 2020-11-30 16-45-46 (7th copy).png: Read-only file system
Archive: /sdcard/data.zip
Rooting phone isn't an option. My questions are -
What can I do here to unzip from the terminal?
Is there any tool to make compressed zip files (in Android) from the terminal?

In order to successfully invoke the unzip command from the terminal you should explicitly specify the folder where the zip's content will be extracted, for instance:
adb shell unzip /sdcard/data.zip -d /sdcard
By invoking unzip --help you will get more information on the other parameters available as well.

Deleting a folder in a AVD

I try to delete a folder with:
adb shell rmdir -f /storage/sdcard/myfolder
adb shell rmdir -r /storage/sdcard/myfolder
and I get the following error :
rmdir failed for -f, Read-only file system
How can I manage to delete that folder, without using java code. The folder is created by my app, so this is no system folder or the like.
* UPDATE *
deleting a file with
rm path/file works, but rmdir doesn't.

adb: command not found in Git Bash

I am using Git Bash on Windows 8. Whenever I type
$ adb devices
I get
bash: adb: command not found
I have already added the path to the PATH variable.

if you haven't solved the problem yet, try adding an alias to your adb.exe
place yourself in the git $home folder
cd $home
if you haven't created the .bashrc file yet
Execute
touch .bahsrc
thereupon
vi .bashrc
add the following line to the file
alias adb='/c/adb/platform-tools/adb.exe'
*note: this path is relative, it depends on where you unzipped the .zip from adb
and save the changes made in vi with ESC then :wq!

GitBash is a Terminal-Emulation software using CYGWIN. The ADB command is a Windows binary that is availabe in a Windows Command Prompt via PATH-variable.
Check this question: Git Bash doesn't see my PATH

It's works my windows machine.
Run the following command on your windows bash profile terminal
echo export "PATH=~/AppData/Local/Android/Sdk/platform-tools:$PATH" >> ~/.bash_profile
Restart your Terminal session
source ~/.bash_profile

Go to My Computer-> Right click -> properties
C:\Users\PCNAME\AppData\Local\Android\Sdk\build-tools

How to delete folders in sdcard of file explorer?

I created several folders in the sdcard (Eclipse) by running an Android application in the emulator. Now I want to delete the folders which I have created on the sdcard.
I am able to delete files in the folders but I could not delete the folders in the sdcard.
How can I do this? Is there a way to delete folders?

Using adb command you can delete folders.
click Run - > CMD-> type adb shell --> cd sdcard -> rmdir {dirname}
Note : Make sure your dir should be empty.
For non-empty directory use.
click Run - > CMD-> type adb shell --> cd sdcard -> rm -r {dirname}

Well, answer from Brijesh Thakur is really helpful.
I just tried this and it worked fine for me to some extent. I would like to mention that if your directory contains any files then the rmdir command will not work. You will have to use rm -r command for that.
To make it more easy for beginners I am explaining the process as follows.
First you need to locate your adb folder, mine was at D:\Android SDK\platform-tools>
Now execute adb shell in a command prompt as:
D:\Android SDK\platform-tools>adb shell
A hash (#) symbol or dollar sign ($) will appear, then enter the following command:
# cd sdcard
Now you are in the sdcard of the device. If your folder is a sub folder then further locate its parent folder using the cd command. Finally, use the rm -r command to remove the folder recursively as follows. This will delete all files and directories in the folder.
# rm -r FolderName
Please note that if you want to remove a single file you can use the rm command only and then the file name (with extension probably). And you can also use rmdir command if the directory you trying to delete is empty.

Using adb shell with rm command you can delete(nonempty as well as empty) folders.
click Run -- > CMD--> type adb shell --> cd sdcard --> rm -r {dirname}

We can do it in a single command line as under:
adb shell rm -r sdcard/<dirname>

If you want to delete everything in your android file system, you need to get its storage name from adb!
# adb shell echo $EXTERNAL_STORAGE
It will give you the path where everything is stored!It will print the storage name in command line, for few devices it is /sdcard and for few, it is /storage/emulated/legacy etc
Now you want to delete everything in that, you need
# adb shell rm -r /sdcard/
that /sdcard/ is not same for all devices, it could be /storage/emulated/legacy/ for some devices!
warning-: It will delete every folder in your file manager except "android" folder
now if you want to delete a particular folder in that file manager
# adb shell rm -r /sdcard/FolderName

remount the sdcard with read and write permission:
adb shell mount -o remount,rw /
Go to adb shell:
adb shell
Delete file you want:
rm -r /sdcard/file_name
It will work most better.
