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.

Now do it with a for loop on every file in a dir with thousands of files
where is the problem? fish shell doesn't split arguments at spaces
$IFS splits files at spaces
IFS is a special shell variable in bash, ksh and POSIX shells that lets you configure how the shell splits words
by default it splits at spaces tabs and newlines
I use
fisha shell that is intentionally not POSIX compatible. While it borrows some principles from Bash and POSIX, it simplifies a lot of things and removes most footguns. Words are split at new lines in fish, which admittedly can also cause troubles, but not nearly as often as in bash and other POSIXy shells.Wtf why would you intentionally not be POSIX compatible?
