This is more of a reminder to myself than anything else. When I am working directly on the Linux server (Centos is my flavor of choice), I often need to find a line number. I have used vi and other editors for a long long time (since the days when unicorns wandered the earth), but I still forget some things. Like today, I had to look up how to turn on line numbers in vi.It really is simple.
Hit the "Esc" escape key and type:
:set number
On some flavors of Linux:
:set nu
also works.
Easy peasy, now if I can just remember this.
