How to automatically execute a shell command after saving a file in Vim?

This is because I'd like to automatica开发者_开发知识库lly run tests after each file save.

I have looked at autocmd and BufWritePost but cannot make it work.

This runs run_tests.sh after any file is saved, with the current filename as the only parameter:

:autocmd BufWritePost * !run_tests.sh <afile>

View the auto-command with:

:autocmd BufWritePost *

And remove all auto-commands from the previous with:

:autocmd! BufWritePost *

put this into your .vimrc file:

(take raml2html doc/api.raml > public/api_doc.html as a command example)

autocmd BufWritePost,FileWritePost *.raml silent! !raml2html doc/api.raml > public/api_doc.html

notice:

• silent! will hide all the output of this command
• :silent if you are using vim7.3-, and silent! if using vim7.3+
• need to quit and restart vim, to make .vimrc take effect.
