Easy (and complex) Search and Replace in Linux Command Line

I wanted to search and replace every file in a directory tree and find a URL that linked to /web-design and remove that part of the URL, and i also wanted to find the phrase “Web Design” in a link and replace it with “Affordable Web Design”.

Usually i would have to go through each individual file via SSH or FTP and then open the file, make the edits, save the file and re-upload the file. The problem with that is, i needed to do this for over 15,000 files on over 3000 web sites, and that isn’t something i wanted to do.

Fix broken image links with javascript

When you have large scale websites that span many servers, sometimes servers go down, and you get a missing image, even if the server is up, you can get corruption loading to a broken image that does not display correctly. This piece of javascript aims to fix broken images on each page load, giving an overall more profesional look. Quite simply, the javascript adds a hook into each image and checks to see if the image has loaded properly or not, and if not, a replacment images is put there instead to make sure that the missing image is auto-fixed for you and the site does not have any missing images.
