I tried to use sort utility and typed sort --help, read one of lines saying its -k option, and part of it:

OPTS is one or more single-letter ordering options [bdfgiMhnRrV], which override global ordering options for that key

I am not getting a clear understanding of the letters option usage.

  • Not an answer, but with GNU sort, the --debug option can be helpful in decipher sort's choices. one example – Jeff Schaller Feb 16 '18 at 17:03

The letters correspond to global options that influence the sort order.

For example:

sort -k2,2nr

means sort by the second column (2,2), numercially (n), in reverse order (r).
