How to make vim use the same environment as my login shell when running commands with “!”?

问题

I use !ls to execute bash command. But after i have configured something like source ~/.usr_profile in ~/.profile file, vim won't source this file as well. So when i want to execute a function declared in usr_profile , i have to run :!source ~/.usr_profile && my_command. When i using this once or twice, it's ok. But when use it frequently, the my vimrc becomes messy.
Is there any better method to solve this problem.Thanks

Adding this line to your ~/.vimrc should solve your immediate problem:

set shell=bash\ -l

When invoked with -l (--login), bash reads your ~/.profile at startup (among other files) and thus everything sourced from there.

When invoked with -i (--interactive), bash reads your ~/.bashrc at startup (among other files) and thus everything sourced from there.

Try $ man bash or :h shell and :h shellcmdflag for more info.

As for the differences between login and non-login shell I must admit my ignorance. This answer on serverfault may help, it's interesting, anyway.
