Re: Installing TeXlive 2021 scheme-minimal: I can't find file `dehypht-x-2021-02-26.tex'

Hi,

I didn't know kpse treats double slashes differently than unix shells do. iirc, unix shells don't care if there is more than one consecutive slash, they are disregarded.

Read a bit about kpathsea, never needed it before, and found out that indeed "two or more consecutive slashes in a path element following a directory d [are] replaced by all subdirectories of d".
Good to know.

But confusing nonetheless, as I didn't know about this "feature" ;) of kpathsea and so it startled me.

Maybe your suggestion of sanitizing the input beforehand is a good choice--assuming that the double slashes actually the root cause of my problem.

Have a nice weekend,

Philipp
