If you hit   and expect to see line numbers  but only see byte counts  then line numbers are turned off  Hit -n to turn them on  and make sure  LESS doesn t include  n    Turning off line numbers by default  for example  setting LESS n  speeds up searches in very large files  It is handy if you frequently search through big files  but don t usually care which line you re on   I typically run with LESS RSXin  escape codes enabled  long lines chopped  don t clear the screen on exit  ignore case on all lower case searches  and no line number counting by default  and only use -n or -S from inside less as needed
