This is my first EE question. I've searched the Linux TA's before asking, but maybe I haven't been searching the right term, because I haven't come across anything that has helped me yet.
Basically, I need to edit a string in several webpages on several different domains, and doing this manually is very time consuming. I'm wanting a shell script to run that will search all the files in a directory, find the old string and replace it with the new string. I'm fairly new to linux and shell scripting, obviously, so please explain your solution so I can learn from your expertise as well as solve my immediate problem.
Thanks in advance. Love the site so far. I found it a week ago, and have learned a lot just from searching various topics...
