This turns the misordered:

$ PATH=/usr/bin:$PATH brew doctor
Warning: /usr/bin occurs before /usr/local/bin

Consider setting your PATH so that /usr/local/bin
occurs before /usr/bin. Here is a one-liner:
  echo 'export PATH="/usr/local/bin:$PATH"' >> /Users/gromgit/.bash_profile
  xzless
  javap
  renice

into the more correct:
