OK, thanks for the suggestion. I don't use set_color in my config.fish or any
of my
custom functions, but I did take a closer look at config.fish to narrow down the
problem. It turns out to have been caused by this statement:
switch $XDG_CURRENT_DESKTOP
case LXDE
set EDITOR leafpad
case Unity
set EDITOR gedit
end
When I log in non-interactively, XDG_CURRENT_DESKTOP isn't set. So switch
doesn't
get an argument, and that seems to cause it to fail in a strange way, with the
above
error messages. Why it leads to errors about set_color and sed, I don't know.
Anyway, I double-quoted $XDG_CURRENT_DESKTOP in that statement, and the problem
is
now solved. Thanks for taking a look.
