Sublime Text 3 comes with a cli tool called subl to work with files on the command line. But it is not available from terminal by default.

In the documentation it is said that this tool is located in /Applications/Sublime folder. And to make it available you should create a symlink in /bin/subl folder.

In OS X the load path be default is /usr/local/bin. So to run sublime from terminal we should place a symlink for it in this folder:

ln -s "/Applications/Sublime" /usr/local/bin/subl

Now I can easily open Sublime Text from the command line:

// opens current directory
subl .

// opens Docs directory
subl ~/Docs
