You need to use the rm command to remove files or directories (also known as folders) recursively. The rmdir command removes only empty directories. So you need to use rm command.
rm command syntax to delete directories recursively
The syntax is as follows:
rm -r dirName
rm -r folderName
rm -rf folderName
In this example, recursively delete data folder:
rm -r /home/vivek/data/
The specified /home/vivek/data/ will first be emptied of any subdirectories including their subdirectories and files and then data directory removed. The user is prompted for removal of any write-protected files in the directories unless the -f (force) option is given on command line:
rm -rf dirname-here
rm -r -f /path/to/folder/
To remove a folder whose name starts with a -, for example '--dsaatia', use one of these commands:
rm -rf -- --dsaatia
rm -rf ./--dsaatia
