I'm sure others will reply with functions etc to do this, but I tend to go for:

* Create a new file
* Enter '1' on the first line
* 'yy' (copy first line)
* '99p' (paste 99 times)
* Ctrl-V (visual block mode)
* G$ (select everything)
* :I (visual increment using Dr Chip's visincr.vim plugin [1])

Alternatively, just use perl:

perl -e 'for($i=1;$i<=100;$i++) { print $i . "\n"; }' > filename.txt

Of course...this is Vim so there regularly a multitude of ways to
accomplish a goal :)

I case you don't want to bother with plugins (I like to keep my
vim installs pretty native so I don't start leaning on things
that aren't baked-in across all the umpteen machines I use), you
can use

yy (yank the initial empty/blank line)
99p (paste it 99 more times to get places to put line#s)
:%s/^/\=line('.') (to put the current line# on each line)

Or most *nix boxes have "seq" available:

:0r! seq 100
and optionally ":$d"/"Gdd" to delete the last/blank line

In Vim7 you'd say for example
:put = range(1,100)

but in Vi ... are you sure you're using Vi and not Vim?

A pure Vimscript method that will work on boxes without Perl or seq
(I'm talking about you, WinXP):

:for i in range(1, 100) | exe "put =" i | endfor

Another approach:

:call append(0, range(1, 100))<cr>

[Dave Land]

Yet another approach:

Insert a new line that contains the number 1.
qq (start recording)
yy (yank the line)
p (put the yanked line)
^A (increment the number under the cursor)
q (stop recording)

You will now have a file with 2 lines in it: 1 and 2.

Now the fun begins:

98@q (repeat the recorded macro [yank, put, increment] 98 times)

[Kevin Dillman]

If you have macro capability:

Insert 1 on the first line.

qf       to begin recording a macro in register f.

yyp    to copy and past the same number on the line below.

C-a    to increment the second number.

q       to stop recording

98@f to run the macro in register f 98 more times for a total of 100.
