indent file from command line without blinking

[Peng Yu]

I use the following command to indent file in command line. But it blinks. Is there a way to let it not blink? Thanks.

vim -n -X -E -c 'normal gg=G' -c 'x' file.sh < /dev/tty

I think it refers to painting the vim GUI, possibly switching to the
alternate screen, then clearing the (possibly alternate screen), then
possibly restoring the (non-)alternate screen, creating a "flash"
effect when scripting vim.

Since this depends on the terminal, you can either pretend using a dumb
terminal:

TERM=dumb vim -n -X -E -c 'normal gg=G' -c 'x' file.sh < /dev/tty

or alternatively use set the `t_ti` and `t_te` terminal options to
empty:

vim -n --cmd ':set t_ti= t_te=' -X -E -c 'normal gg=G' -c 'x' file.sh < /dev/tty

I still get something printed. How to turn it off? So `< /dev/tty` is
not needed anymore for both cases?

Use the :silent modifier?

Seems not to be easily possible.
