or (depending on circumstances)
1) marginally faster (I think) than the above; also compatible with Vim
versions earlier than 7:
let i = 1
while i <= line('$')
" do something; i is the line number
let i += 1
endwhile
2)
:1,$call MyFunction()
" if MyFunction is defined without the "range" option
" it will be called once on every line in the file.
" if it has the "range" option it will be called just once.
" In either case, within the function,
" a:firstline and a:lastline will be set
" to what their names imply.
3)
:1,$g/^.*$/command
" where "command" is any ex-command: it will be executed
" once on every line which matches the pattern, so here
" I chose a pattern which matches every line.
4) to execute some ex-command only on lines containing something other
than whitespace
:1,$v/^\s*$/command
Best regards,
Tony.
