There is root ownership and root group applied to /media/pandya/Ext4/*
("pandya" is user-name). To apply group "pandya" I run following command:
sudo chown -hR root:pandya /media/pandya/Ext4/*
Now, There is root ownership and "pandya" group applied to /media/pandya/Ext4
and all sub files and directories.
But group "pandya" has only permission "Access files" (for directories) and "Read Files" (for files) for all sub directories and files.
So, How to apply full permissions ("create and delete files" to directories and "read and write" to files) to group "pandya" ? So-that I can fully access /media/pandya/Ext4/
and all sub directories and folders with "pandya" group.
chmod g+w
. To make all subfolders accessible, you will need to add the executable bit to them but you cna do so (for directories only) usingfind /media/pandya/Ext4/ -type d -exec chmod g+x {} +
