adb command not found after installed it

Use this command for adb installation:

apt install android-tools-adb

1. Download the Android SDK Platform Tools ZIP file for Linux from this link.
2. Move the file to the location you want to store adb using the following command sudo mv filename.zip /wanted/location/.
3. Extract the ZIP with unzip filename.zip command.
4. Enter to platform-tools/ directory with cd platform-tools/
   • if you are not in the extracted directory use the full PATH cd /home/user/directory/platform-tools
5. Now you can use the adb tool from inside the platform-tools directory using ./adb [options] for example ./adb version.
