Sort text based on 5th column with the trouble at 1st having sub columns
by zeroone from LinuxQuestions.org on (#6DT13)
How to sort, by CLI utility or Bash codes, a plain text page, based on 5th column out of 6 columns regarded by human but not by machine as the first column has 1-4 sub columns, means 1, 2, 3, or 4 words, i.e. non-space strings, with its starting word is always started with alphabet but not always for the other words if any, and the rest columns is only one single word i.e. one non-space string ?
