From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Find can actually do the sed itself if you don't want to use a subshell and a shell loop.
-print0 | xargs -0 sed -i
to get a single sed process working across multiple files.Add a
-P 8
to xargs to get 8 parallel processes.Today I learned that xargs supports parallelization natively! That's gonna make some of my scripts much simpler
Change the ';' to a '+' for even more efficiency (no need to fork+exec a sed process per file, sed can take multiple files)
+1
And
In the off chance the files are not under git or some other VCS, might be a good idea to add the -b option to backup
