You were very close. One reason it didn't work was because the
:scriptnames command put Vim into interactive mode (my term) when it
issued the "-- More --" prompt and Vim stayed in that mode. The
other problem was that the :scriptnames command writes to the
screen, not to a Vim buffer, so there was nothing to write to your
file. Here is a version that works.
vim +"set nomore" +"redir > vim_output" +"scriptnames" +"q"
The "set nomore" stops that "-- More --" prompt. The "redir >
vim_output" sends the output of the subsequent commands to the file
vim_output". The "q", of course, quits Vim. Note, though, that
none of those commands start with ":". They could, but it's
unnecessary.
