How to open some files based on extension rather than mime type?

[Israel]

Hi John,
Thanks for finding this!!
I will have to experiment with using mimeapps.list some.
For all who are interested here is the spec...

$XDG_CONFIG_HOME/$desktop-mimeapps.list 	user overrides,
desktop-specific (for advanced users)
$XDG_CONFIG_HOME/mimeapps.list 	user overrides (recommended location for
user configuration GUIs)
$XDG_CONFIG_DIRS/$desktop-mimeapps.list 	sysadmin and ISV overrides,
desktop-specific
$XDG_CONFIG_DIRS/mimeapps.list 	sysadmin and ISV overrides
$XDG_DATA_HOME/applications/$desktop-mimeapps.list 	for completeness,
deprecated, desktop-specific
$XDG_DATA_HOME/applications/mimeapps.list 	for compatibility, deprecated
$XDG_DATA_DIRS/applications/$desktop-mimeapps.list
distribution-provided defaults, desktop-specific
$XDG_DATA_DIRS/applications/mimeapps.list 	distribution-provided defaults



Based on that I think you should save the file as (for local users):
~/mimeapps.list
~/lubuntu-mimeapps.list (mayeb lxde??)


then run
echo $XDG_CONFIG_DIRS
if you want to find the specific global directories to change the
## I am using an array here below to indicate you can *probably* use any
directory listed)
${XDG_CONFIG_DIRS[*1*]}*/mimeapps.list*
or one of these:
lubuntu-mimeapps.list
lxde-mimeapps.list
