How to run Vim command from the shell?

Question

This might be a dumb question, but bear with me.

I'm automating some of the usual stuff I do when setting up a new work environment, and would like to automate the Vim command :BundleInstall (for installing all my Vim plugins).

Is it possible to run this from the shell?

Alternatively, is it possible to have the script run Vim, execute :BundleInstall, wait until it finishes and quit?

Thanks.

Answer 1

From the vim(1) man page:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used). Example: Vim "+set si" main.c

Note: You can use up to 10 "+" or "-c" commands.

Answer 2

While the vim specific recipe above is the right way to do it, you can always use a more general approach like autoexpect.

Answer 3

You can execute your command like this:

vim -E -c BundleInstall -c q

which will avoid opening a Vim window in your terminal.

Note: My first answer included the -s option which I had needed for another application but was incorrect here because it prevented much of Vim's intialization including sourcing the plugin that defined the BundleInstall command.
