Alternative to SSH command line from Ubuntu

Look into installing sshfs if you're on Linux. You can remotely connect to a machine over ssh, but it will show it as part of the file system on your local machine, so you can edit files in your local editor, and treat it as if it were a local file. You don't even have to install anything on the server side, it all just works off of ssh.

Similarly, there is win-sshfs for windows, which takes a similar approach to sshfs, but instead mounts the file system as a Windows network drive. Thanks for the recommendation Lexi R!

Another alternative would be using FTP to grab the files and put them onto your local machine, view and edit them as you'd like, then use FTP to put them back in place. You'd need a FTP server on the CentOS box, and you can use something like Filezilla to connect.

If you are running the connection from Windows, you can check out WinSCP. It is free, and gives you a tree-view (Explorer-like) of the file system that you have access to.

If you are running from a *nix environment, you'll need to enable some sort of file access to it, such as FTP (insecure), SFTP (secure), or you can mount the remote filesystem as a CIFS, NFS or sshfs file system. All these options are free, and should be built in to your OS.
