I’ve recently learned that in Linux, you can use emois in filenames. I died a
littlelot inside when I learned that.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.”
I once accidentally created a file with a newline character in it… it was pretty tricky to fix from command line.
This is why you shouldn’t parse
lsoutput btw. Usefindandreadinstead
I actually did this a lot on classic Mac OS. Intentionally.
The reason was that you could put a carriage return as the first character of a file, and it would sort above everything else by name while otherwise being invisible. You just had to copy the carriage return from a text editor and then paste it into the rename field in the Finder.
Since OS X / macOS can still read classic Mac HFS+ volumes, you can indeed still have carriage returns in file names on modern Macs. I don’t think you can create them on modern macOS, though. At least not in the Finder or with common Terminal commands.
I created a file with backspace in name, it was hard to understand why filename doesn’t match
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.
You can have new lines in your file names. YSAP has a good video/playlist about how to deal with these and many more.
could you have
..? I assume most terminals would just spell out.\x200b.?Or use a hair space so it looks almost the same. Or … but you’ve added the right-to-left unicode character. I’m guessing there’s something that looks a lot like a period, too.
If ext4 doesn’t include restrictions terminals probably should.
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
.XComposefile to throw some gr∑∑k letters around, for instance, like some confused script kiddie. :)On topic: There are multiple variants of spaces in Unicode. You’re welcome, and now go and create something utterly deranged with that information.
I already deal far too much with trying to handle dumb fucking typos in employee data, and trying to turn human names into valid email addresses.
The first time I encounter something like this there will be a body. It will not be found.

Some grSSk letters?
yes, grSSk letters
I’m just gonna pretend I didn’t hear that.

I think that may be possible for every filesystem supporting UTF-8 encoding.
Same for Windows (11): I just renamed a file to an apple emoji
You can use emojis for variable names in swift code.
I\ don\'t\ know\ what\ you\ mean,\ I\'ve\ never\ encountered\ any\ annoyances.
'I don\'t know what you mean, I\‘ve never encountered any annoyances.’
Single quotes don’t allow any escaping in shell, you need
'I don'\''t know what you mean, I'\''ve never encountered any annoyances'Or, in Zsh with
setopt rcquotes:'I don''t know what you mean, I''ve never encountered any annoyances'Oh right, good catch. That’s me shell scripting while in a meeting. 🫠
Good use of a meeting to be fair
it works in fish
Are you typing the whole filename by hand? Tab expansion exists, you know?
If it fucking works…
Sometimes it does. But not always.
Zsh changed my life, but I still hate escape chars in my command lines for readability reasons
Now I use lowercase and underscores everywhere.
This is the best for tab completion, altho I prefer hyphens visually
the struggle between spaces in filenames look cute and oh fuck what’s the code to reference a space in a filename in terminal?
I very intentionally have all my code in
Personal Projects 🥰andWork Projects 🏦directories so I can find bugs in the handling of file paths." is your friend
Yep, exactly. And tab. \<space> is weird at first but makes sense if you think about it
not sure why the default behavior is this:
file\ name\ with\ a\ bunch\ of\ spacesinstead of this:
"file name with a bunch of spaces"but you can just press
"before pressing tab to auto-complete, and it will use the 2nd formI mean, at least in Bash tools like
lsdo use quotes by default:$ ls filename_without_space 'filename with space'But yeah, tab expansion uses backslashes, sadly.
Windows is stupid as shit, trying to shift+right click > open Powershell in a path containing a space results in it throwing an error, and you have to paste the path in yourself anyway
smells like skill issue tbh
tools which cant handle being installed/run on directories with spaces are so annoying
tools which cant handle being installed/run on directories with spaces are unacceptably common
My work has me working with Matlab Simulink paths, which may (and sometimes actually do) contain newlines.
Don’t try svelte kit. This is pseudocode but it’s valid. The only symbol show here that is not real is the / that I’ve placed at the end of folder to show that they are folders. There are other special cases
routes/ +page.ts (admin)/ +page.ts [user=uuid]/ [[community]]/ +page.ts posts/ [...postIds@]/ +page.tsI still use spaces
agreed, “still worth it”
I do, however, tend to keep spaces out of my folder names so i can just use quotes at the end.
