Re: Large file - Opening n head lines

Hi All,

Is it possible to open a Large File Vim but just only few beginning lines of it, edit one of these 50 first lines and then save and quit ?

Thank you

NV

Inserting data, in general case (i.e. if the size may change), is non-trivial. That is, one has to append a copy of the original file's tail and then flush everything to disk again.So even if you do

    :read !head -n 20 foobar.txt

and edit it, you still must do

    :saveas temp

    :!tail -n +21 foobar.txt >>temp

    :!mv temp foobar.txt

to create a new version. And it does not look like some gain to me.

Regards,

Matvey
