for example, 5,8c5,11 mean. or can advise how use it. have read documentation still find difficult. can offer general advice?

these change commands (to edit files) can convert 1 other.

the normal output format consists of 1 or more hunks of differences; each hunk shows 1 area files differ. normal format hunks this:

change-command < from-file-line < from-file-line… --- > to-file-line > to-file-line…

see info diff detailed explanation of these commands.
