    Needs to be extended to coexist with other OS native cli open applications.

    CLI_OS="na"

if $(echo "${OSTYPE}" | grep -q msys); then
  CLI_OS="windows"
elif $(echo "${OSTYPE}" | grep -q darwin); then
  CLI_OS="mac"
else
  CLI_OS="linux"
fi

    Many ways to do the same task, humans are awesome!

    # OS specific support (must be 'true' or 'false').
cygwin=false
msys=false
darwin=false
linux=false
case "`uname`" in
  CYGWIN* )
    cygwin=true
    ;;
  Darwin* )
    darwin=true
    ;;
  Linux* )
    linux=true
    ;;
  MINGW* )
    msys=true
    ;;
esac

    • mac

      • open -a …

    • linux

      • xdg-open $file
