[SOLVED] bash globbing: ls not accepting regex properly?

[devnulljp]

Weird, ls isn't accepting regex properly

ls *.pdf
ls: invalid option -- '9'

Can't escape it either

ls \*.pdf
ls: cannot access '*.pdf': No such file or directory​

Something is broken with bash globbing.

works with other file types

ls *.txt
ls *.jpg

just ls *.pdf doesn't work? How does that make any sense? (And yes there are pdfs in the directory)

Checking, it works in other directories -- why would it not work in my Downloads directory but everywhre else?

Workaround:

ls ./*.pdf

or

ls -- *.pdf

EDIT: Figured it out. There's one pdf in there with a filename starting with a "-" so ls is interpreting that as an option
Totally my fault for not seeing it.
