Run terminal command from VIM?

I wish to write a function which I can add to my .vimrc file that will call a terminal command, and then bind it to <leader>u.

I cant seem to get it to work tho. I believe that I can use the system() function, but there is very little documentation available and I cant seem to get it to work.

The terminal command in question is 'git push origin master'.

I know that there are plugins available for git but I am not looking for any of these, just a simple function to bind a terminal command to a key combination.

function gitPush()
 system("git push origin master")
endfunction
:nmap <leader>u :call gitPush()

I know this is waaay out, but vim doesnt seem to want to make documentation very available.

Why do you use call to call your own function and fail to use it for builtin? It is one of three errors, other was mentioned by @Richo: user-defined function must either start with a capital or with b:, w:, t: (note that neither of these are local functions), g:, s: (only inside scripts, and you will have to replace s: with <SID> in mappings), even \w: (for example, function _:foo() works) or with {filename_without_extension}# (if filename matches \w+.vim). If it is anonymous function:

let dict={}
function dict["foo"]()
endfunction
function dict.bar()
endfunction

it also does not require to start with a capital. So the correct solution is:

function g:gitPush()
  call system("git push origin master")
endfunction
nnoremap <leader>u :call g:gitPush()<CR>

Third error is omitting <CR>. I changed nmap to nnoremap because it is good to use nore where possible. Having : at the start of the command does not hurt and is not an error, but I just do not write it: it is required in normal mode mappings to start command mode, but not inside scripts.

function GitPush()
    !git push origin master
endfunction

Is the way to run a command in a subshell.

EDIT: User defined functions must begin with a capital letter too ;)
