<div dir="ltr"><div>Yes, you are right. I got confused by the combination of a very long

I updated to the latest Ubuntu with TeX Live 2022/dev/Debian. <br>
...<br>
very long filenames stopped working<br>
<br>
Please provide the actual case that failed, and any error messages.<br>

It's improbable that any filesystem-related bug is the same on Windows<br>
and Unix. The code is very different.<br>
<br>
In any case, I can't reproduce the two cases in this report with current<br>
(that is, 2022) TL on x86_64-linux (specifically Alma Linux 8.7, but it<br>
shouldn't matter). Either a deep directory name under /tmp, or a long<br>
filename, or both, all worked.<br>
<br>
FWIW, the "long" filename in that report is "only" 117<br>
characters, which I wouldn't expect to have problems on any Unix-ish<br>
system.<br>
$ echo identify_conic_sections_written_in_rectangular_coordinates_by_eccentricity_and_write_the_equation_of_the_conic_1.tex|wc<br>
1 1 117<br>
<br>
Running the long directory name with the long filename:<br>
<br>
$ xelatex /tmp/abcdefghijklmnopqrstuvwxyz/0123456789/abcdefghijklmnopqrstuvwxyz/0123456789/abcdefghijklmnopqrstuvwxyz/0123456789/abcdefghijklmnopqrstuvwxyz/0123456789/abcdefghijklmnopqrstuvwxyz/0123456789/abcdefghijklmnopqrstuvwxyz/0123456789/abcdefghijklmnopqrstuvwxyz/0123456789/identify_conic_sections_written_in_rectangular_coordinates_by_eccentricity_and_write_the_equation_of_the_conic_1.tex<br>
This is XeTeX, Version 3.141592653-2.6-0.999994 (TeX Live 2022) ...<br>
.. reads file fine ...<br>
<br>
Best,<br>
