Sublime Text 3 includes a command line tool, subl. However, it does not work out of the box after you install the editor in OS X Yosemite.
After the installation, create a symbolic link to Sublime Text using this command:
ln -s /Applications/Sublime Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl
- ‘/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl’ is the location that the application is stored in your Applications directory. - ‘/usr/local/bin’ is the chosen path you want the symbolic link to be located.
To use Sublime Text as the editor for many commands that prompt for input, set your EDITOR environment variable:
export EDITOR='subl -w'
where the flag -w will cause the subl command not to exit until the file is closed.
You can also set your default editor in Git with this command:
git config --global core.editor "subl -n -w"
