Problems using subl command in terminal: "Command not found" & "No such file or directory"

Run each command in the Terminal (in this order):

$ sudo rm -rf /usr/local/bin/subl
$ sudo ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/local/bin
$ subl .

This should work!

Note: First you should check that your sublime's app is in Applications folder and it's name is Sublime Text 2, if not, you should change the name in the second command and type the name of sublime's app.

if you are using RVM, do this:

ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/.rvm/bin/subl

For El Captain or later OS:

In El Capitan, you are not allowed to write to /usr/bin, but writing to /usr/local/bin is ok. By default, /usr/local/bin should also be in your path variable.

For Sublime Text 3

sudo rm /usr/local/bin/subl
sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl

For Sublime Text 2

sudo rm /usr/local/bin/subl
sudo ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl
