my site have 5000 URLs (at least). all pages end with *****.html , they are not php or shtml. now i have problem because of my 5000 pages.
i run ads in my site, and ad codes are in every single page, now i switching to another ads network, so i need to remove all old codes and insert the new codes in every single page.
so its a hard job to insert the codes in every page, but this is not the problem now, my problem is what i can do now can help me and make my job much easier in the feature if i want to change the codes again.
If the old code are all the same in different pages.
Just use a tool to find and replace for all your files. Since there are 5000 html pages, I think you may need to replace them use command console. As far as I know, in Linux, you can use some command with regular expression to do the work pretty quickly. I suppose it will apply to DOS as well.
If you search this board for "search and replace" you will find lots of solutions. Mine would be to use Homesite's search and replace method and re-upload the files, OR write a small perl script to do the work for me directly on the site.
