I have an xinit script which outputs the display id to a file with the

xinit .. -displayfd 3 3>$HOME/.display
Thanks for reporting this.
For future issues, can I ask you to use the cygwin list, per [1]
[1] https://cygwin.com/ml/cygwin-xfree-announce/2015-03/msg00001.html
I hope you mean ' xinit -- -displayfd 3 3>$HOME/.display'
This outputs correctly '0' but appends 0x00 and 0x0A. Why is it
outputting a null byte and this 0x0A?
Yeah, this seem to be a bug in xinit (which needs to insert itself into
the displayfd pipeline to learn the display number for it's own purposes)
$ X -displayfd 3 3>~/.display
[...]
$ xxd ~/.display
00000000: 300a 0.
$ xinit -- -displayfd 3 3>~/.display
[...]
$ xxd ~/.display
00000000: 3000 0a 0..
This is causing issues where I try to perform:
echo $(cat .display)
Which results in:
bash: warning: command substitution: ignored null byte in input
0
This warning is new in bash 4.4, I think.
I think this is a just a warning though, and shouldn't actually cause
any issues?
