>My debian distro looks for such things in /etc/mailcap. I'd look there first.
Thanks! ...but I suspect that may be a Clupea harengus of the crimson variety :-), partly because it was last modified more than a year ago: $ ls -l /etc/mailcap -rw-r--r-- 1 root root 272 May 5 2020 /etc/mailcap ...but mostly because it's almost empty: $ cat /etc/mailcap ### ### Begin Red Hat Mailcap ### audio/*; /usr/bin/xdg-open %s image/*; /usr/bin/xdg-open %s application/msword; /usr/bin/xdg-open %s application/pdf; /usr/bin/xdg-open %s application/postscript ; /usr/bin/xdg-open %s text/html; /usr/bin/xdg-open %s ; copiousoutput I'm not going to speculate on why an Arch-derived distribution has an /etc/mailcap sourced from Red Hat. :-/ Just for fun I tried $ /usr/bin/xdg-open /tmp/session2.mp3 I'm not sure why xdg-open decided that I want to open .mp3 files in clementine (that's a question for another time), but in fact it did so with no output other than debug messages from clementine (and why so many debug messages are emitted is also a question for another time). - Steven -- ___________________________________________________________________________ Steven Winikoff | Montreal, QC, Canada | For clarity in writing, be careful about s...@smwonline.ca | word selection.
