extract-files.sh won't extract proprietaries from /system/bin - Android Q&A, Help & Troubleshooting

Ok so I'm trying to extract propritaries from my phone script starts and extract files but it won't extract files from /system/bin and /xbin while files from /system/lib are extracted without any problems, I checked permissions and they are same for those folders (755).
I checked for files and they are there, they exist on phone while adb states otherwise.
Note that I don't have root and don't have a good way to do that.
here is extract-files.sh and proprietary-files-mtk.txt

What I am understanding from this post is that you have a script to extract files from your /system/bin directory for your phone? Since you have adb, go to adb shell and type in whoami. If it says shell, then you're not root and can't proceed further. If it says root, then do mount | grep system. If it shows system is ro, then you need to remount system by using mount -o rw,remount /system and make sure doing mount | grep system shows rw. It should work then.

Why would I need rw permission on /system/ when I just want to pull files from it, not to push, and also why then it works with /system/lib/ folder, both have 755 permisons, and pull from /lib/ folder works but not for /bin/ and /xbin/ ?
It doesn't say permission denied it says file does not exist which is false because file does exist.

It's because of your phones security. Look at the following files from my phones /system/lib. You can see, they're root group and only root user can modify them or even take them off device. Which means, you need to be root user to make any modifications to them.
drwxr-xr-x 2 root root 4096 2008-12-31 10:00 soundfx
drwxr-xr-x 3 root root 4096 2008-12-31 10:00 ssl
lv7:/system/lib #
Going to /system/bin ...
lrwxr-xr-x 1 root shell 6 2008-12-31 10:00 xxd -> toybox
lrwxr-xr-x 1 root shell 6 2008-12-31 10:00 yes -> toybox
lv7:/system/bin #
The following files are part of root group but shell user. So if you do the command "whoami" and are shell user, you can change these files and extract them off your phone.
The permissions don't matter here, you need to be root user and have rw permission on system. If you can give me the code of your script, I can tell you what it is doing. If I were you, try using the command prompt and use the adb pull command and it will give you the permission denied error.

I used adb pull and it gave me same error, "file does not exist".
Why would I need rw permission when I only want to read file not modify it.
I pulled whole bin folder and when pulled it has missing about 100 files every one I have needed was in that 100 files. However I give up and just copy files to sd card from total commander and transfered them via USB to PC
