Thanks.

to Avoid the find . you can do something like this:

upsearch () {
  slashes=${PWD//[^\/]/}
  directory="$PWD"
  for (( n=${#slashes}; n>0; --n ))
  do
    test -e "$directory/$1" && echo `readlink -m "$directory/$1"` && return 0
    directory="$directory/.."
  done
  return 1
}

projectDir=`upsearch s-project.json`
if [ $? -eq 0 ]; then
  echo "Found = $projectDir";
fi

The upsearch function search for a specifical file name starting from current directory recursively up.
If it find it it echo it and return 0, if not return 1.
you can get the result, check if it found it and then use that for the find command. This assure you do not run find on root directory (unless someone place the s-project.json file in the root directory).

I created a fork fixing the find . issue

Awesome @danielesegato, thank you very much! Only one thing prevents me from using your script: I'm using OS X and the readlink command is apparently different from the Linux version. Do you know any workaround for this?
