Hallo,
can I save buffer that is not current one?
something like that:
(setq buf (find-file-noselect "/some/file"))
(save-buffer buf)
I see that 'save-buffer' does not get any parameter:(
best regards
Michal

Well, then you should make the buffer you want to save the current one:
(save-excursion
(set-buffer (setq buf (find-file-noselect "/some/file")))
(save-buffer buf))
save-excursion will make sure that the current buffer is restored when
you're done.
HTH,
Anselm

But what you really want to do is probably:
(let ((buf (find-buffer-visiting "/some-file")))
(when buf
(with-current-buffer buf
(save-buffer))))
Because you probably don't want to find the file if it isn't already
open.
