In filenames? AMATEURS! Use obscure Unicode in your passphrases for maximum security. Ctrl-Shift-U, enter arbitrary code point, bam! 🦊
Works even better with a Compose key and a nice, chonky .XCompose file to throw some gr∑∑k letters around, for instance, like some confused script kiddie. :)
On Linux file systems you can use any character except NULL, and / is a reserved character.
E.g. on ext-4 “All characters and character sequences permitted, except for NULL (‘\0’), ‘/’, and the special file names “.” and “…” which are reserved for indicating (respectively) current and parent directories.”
So … is allowed, or all whitespace, or Zalgo text.
I mean, on the one hand, I guess why be restrictive, but on the other I feel like requiring something that looks like language somehow might be a good idea to avoid edge cases and attacks.
This was quite a while ago now, but I don’t think my shell escaped the tab complete properly, I remember it just printing a literal newline and evaluating it as a second command. I think there was other unicode in there too, otherwise I would have just typed it out. I had to do something with null terminated output and piping it in to mv, but I can’t remember what exactly.
it was on accident, habibi, I swear 😁. I messed up some cmake code for preprocessing .txt ascii sprites into constants and accidentally created this abomination
I’ve recently learned that in Linux, you can use emois in filenames. I died a

You can have new lines in your file names. YSAP has a good video/playlist about how to deal with these and many more.
I once accidentally created a file with a newline character in it… it was pretty tricky to fix from command line.
Did you not just use tab? That’s the usual method of dealing with weird characters in filenames that I’ve found
