Your command
sudo ln -s "/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl" /usr/bin/subl
has "/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"
both in quotes and with an escaped space between Sublime
and Text
. Use one or the other.
So, first run
sudo rm /usr/bin/subl
to get rid of the old, incorrect symlink. Then, run
sudo ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" /usr/bin/subl
(without the escape) and you should be all set.
