Did you ever have to substitute a single word with another one in lets say… 200 files? I just had to, since I used some old files from a client and wanted them to work in the new project – where some classes where named different because of Propel stuff. Here’s my solution:

find . -type f | while read a; do sed -i 's/Old/New/g' $a; done;

If put into words it reads like:

Find all files from here deep in all sub-directories and for each of them let sed substitute the word Old with New, please do this globaly in those files, and in place. Thanks sed, you saved my day.
