Use Bash instead of realpath to get real path

Using realpath transforms a local path into a full one, or keeps the same path if it is already a full path.

some -> /home/rwxrob/some
/home/rwxrob/other -> /home/rwxrob/other

This can be done in Bash without calling realpath:

if [[ $0 =~ ^/ ]];then
  echo "$0"
else
  echo "$PWD/${0//\.*\//}"
fi

POSIX shell cannot do this because it cannot examine just the first character of $0 without calling out to a subprocess so might as well just use realpath for that.
