I suspect that the empty file problem you're seeing is actually a
regession bug in fish. Specifically, I belive the file in question
does contain the file name, but does not end with a newline, and that
the fish prompt 'swallows' the output. You can test this theory by
calling echo after cat-ing the file. The next fish release will fix
this problem.
The following script seems to work correctly for me, though the choice
of filename leaves something to be desired:
function mc
set tmpfile ~/ggg
command mc -P $tmpfile
cd (cat $tmpfile)
rm $tmpfile
end
I did run into some issues with mc, e.g. when I specified a relative
directory path for the -P file, the file seemed to get completely
swallowed.
Hope this helps!
