LINUX IS CONFUSING. THESE ARTICLES SHOULD HELP.
Linux has a rich set of commands for manipulating and accessing files. The du utility gives information on disk usage, and the sort utility can sort the results. Finally, we can run those results through the head command, which gives you the top 10 lines outputted through any other command. We’ll chain the commands together to get the output that we want.

If you are getting this error then you probably reset the permissions on your hidden .ssh directory in your user folder, and your keys aren’t going to work anymore. It’s very important that these files not be writable by just anybody with a login to the box, so openssh will give you an error if you try to use them.
If you want to “map a drive” from a Linux computer to a shared folder on a Windows computer or a shared folder on a Linux computer running Samba, there’s a simple way that you can do this from the command line.
