Command Line File Replace

[MissingLink]

Hi there

I am newer than new to Linux, but need to do some editing of html documents that are sitting on a linux computer.

I am running an application utilising rPath and Red Hat Linux nash version 4.2.15. This application has a web interface that can be accessed from remote computers over a network. I need to change some of the images in the web interface. I have located, through bash commands, where the images reside on the box. Now I need to know how I can replace these files remotely? And is there a way for me to copy these files from the box to a remote computer and visa versa?

Thanks in advance
