less command
less packs more power than “more” or “tail” commands
tail -f like functionality
Usage: $ less +F file.log
If only $ less file.log is invoked pressing F will switch back to mode similar to tail -f
Enable row number
-NR inside less enables row number
Disable wrap
-S toggles word wrap
Finally, launching less with the following does it all
less +F -NR file.txt
Opening compressed .gz files with less
