I wanted to get that warning out quickly. Now I have time for some
explanation.
(1) My good ~/.trinity has precisely 0 files with 770 permission. Don't
wreck yours. Another suggestion was made for 700 permission. Well
my ~/.trinity does have 951 files with 700 permission but they're
still the minority. For example I have 2049 files with 600 permission.
DON'T MASS-BORK YOUR PERMISSIONS. UNLESS YOU CAN RESTORE FROM A
BACKUP, RECOVERY COULD TAKE DAYS OF WORK.
(2) Commands such as those above should not be linked by pipe "|". They
should be linked by semicolon ";" or in some cases ampersand "&".
When commands are linked by pipe the output of one is fed as the
input to the next. Even if the next ignores the unwanted input
this can still cause problems. Consider "ls | ls". If the second
ls finishes before the first the pipe breaks and the first ls is
prematurely terminated. If that first ls was instead a command
changing every file in your ~/.trinity it would be killed at an
arbitrary point in the proceedings instead of completing its job.
So what should you do instead of borking your ~/.trinity?
find ~/.trinity -not -user U -o -not -group G -exec ls -dl {} \;
Replace U with your user and G with your group in the above.
If the resulting files look like they should belong to you then you
can:
chown -R U:G ~/.trinity
