Automatically open Sublime Text projects in a directory

I usually start Sublime Text 2 from the command line to work, depending on the case, on the content of a directory or on a project (materialized with a *.sublime-project file).

It ends up with one of the following commands :

• subl .
• subl my-project.sublime-project

Here is the snippet I added to my .bashrc file to have the subl command automatically “guess” what I want. It does the following:

• If a path is given (subl "my/file.txt"), it opens the file.
• If nothing is given and a .sublime-project file exists in the current directory, it opens it
• If nothing is given and no .sublime-project file has been found, it opens the folder.

function project_aware_subl {
  project_file=$(ls *.sublime-project 2>/dev/null | head -n 1)
  subl ${*:-${project_file:-.}}
}
alias subl="project_aware_subl"
