Auto generate Line Numbers
How do I generate line numbers in Vi?

I have this:


Code:
,'04-90020-039N','61423','2GDV00039-0002', SYSDATE);
,'04-90020-040D','61423','2GDV00046-0001', SYSDATE);
,'04-90020-041N','61423','2GDV00038-0002', SYSDATE);
,'04-90020-043D','61423','2GDV00047-0001', SYSDATE);
,'04-90020-044D','73168','2GDV00071-0002', SYSDATE);
,'0453-941-110','1DJ82','0453-941-110', SYSDATE);
,'0456-931-110-01','1DJ82','0456-931-110-01', SYSDATE);
,'0456-933-111','1DJ82','0456-933-111', SYSDATE);
,'0N687022-509','11447','2ZKH85070-0005', SYSDATE);
,'1000538','83330','1000538', SYSDATE);

And I want to put a line number in front of the line. This goes on for 23k+ lines.

Code:
1,'04-90020-039N','61423','2GDV00039-0002', SYSDATE);
2,'04-90020-040D','61423','2GDV00046-0001', SYSDATE);
3,'04-90020-041N','61423','2GDV00038-0002', SYSDATE);
4,'04-90020-043D','61423','2GDV00047-0001', SYSDATE);
5,'04-90020-044D','73168','2GDV00071-0002', SYSDATE);
6,'0453-941-110','1DJ82','0453-941-110', SYSDATE);
7,'0456-931-110-01','1DJ82','0456-931-110-01', SYSDATE);
8,'0456-933-111','1DJ82','0456-933-111', SYSDATE);
9,'0N687022-509','11447','2ZKH85070-0005', SYSDATE);
10,'1000538','83330','1000538', SYSDATE);


thanks.

try (if your vi version supports setting regular expressions for replacement) for updating lines with line #:
Code:
:1,$s/^/\=" " . line(".")/

If the vi does not work, this will work:
Code:
nl -s "" infile | sed "s/^ *//"

Or, you can do same in vim, maybe other vi versions:
Code:
:1,$ !nl -s "" | sed "s/^ *//"

Or, vi has the :set nu command in case that is what you are looking for.
