You could easily expand it, if you use SVN or have other folders you want to preserve — just match against more names. It’s roughly equivalent to -not -path .git, but more efficient, because rather than checking every file in the directory, it skips it entirely. The -o after it is required because of how -prune actually works.

What’s the difference between PCRE and recursive regex?
This explains the differences in behavior between the two engines—which, if you insist on knowing at this early stage, pertain to atomicity and the carryover of capture buffers down the stack. When Perl introduced recursion into its regex it behaved differently from PCRE’s, and PCRE stuck to its original behavior for backward compatibility.
How to do search and replace in Linux?
In the Linux command line, we can do text substitution and save the result back to a file in many ways. To solve this problem, we’ll pick the sed command to do the search and replace job.
