how to remove folder in terminal linux
To remove an empty directory, use the rmdir command as follows:
$ rmdir foldername
If the directory still contains files or subdirectories, the rmdir command does not remove the directory.
To remove a directory and all its contents, including any subdirectories and files, use the rm command with the recursive option, -r.
$ rm -r foldernam
