If you have ever used Dreamweaver, you are probably familiar with the Global Search and Replace feature, which allows you to search and replace amongst all files with in a site, which can be very handy if you are doing a static site. If you are too hard core for Dreamweaver though, and you spend your whole day buried in a terminal window, how can you achieve the same thing? By this piece of bash-trickery, that’s how:

find . | grep html | xargs -t -I {} sh -c "cat {} | sed 's/Stuff to find/Replace with this/' > {}"

1. find . – find all the files from the current directory down
2. grep html – filters the output to include only filesnames with html in them
3. xargs -t -I {} sh -c – pumps the file names into the cat command, but also sets a variable called {} that holds the filename
4. sed ‘s/Stuff to find/Replace with this/’ – just a search and replace
5. > {} – save the output back to the original file name A word of warning though, leave the last bit off until you are sure your output is correct, because there is no undo feature :)
