I am not aware of any such client, though I would think there is at least one out there. Linux does have several nice GUIs that accomplish this, such as Nautilus (the Gnome file browser) and Konqueror (the KDE file browser).
One tip for when you're using the command line. Use the tab
key for auto completion. When you are typing just hit tab
and it will complete program names, file and directory names, and when there are multiple matches it will list them after two tab
key presses. This will help you catch typos and prevent them as you are constructing a command. This page will give you a bit more info: http://www.linux.com/articles/54005
