Saving with CTRL-s in vim

Question

I have added this line in .vimrc so that pressing control-s saves the current file

:nmap <C-s> :w!<cr>
:imap <C-s> <esc>:w!<cr>

But this is not working. Any suggestions about what I am doing wrong?

See this wikia.com article for the exact thing you're tyring to do: http://vim.wikia.com/wiki/Map_Ctrl-S_to_save_current_or_new_files

In a nutshell you need to do the following.

1. Add this to ~/.vimrc

" If the current buffer has never been saved, it will have no name,
" call the file browser to save it, otherwise just save it.
nnoremap <silent> <C-S> :if expand("%") == ""<CR>browse confirm w<CR>else<CR>confirm w<CR>endif<CR>

2. Disable terminal's interpretation of Ctrl+S

# bash
# No ttyctl, so we need to save and then restore terminal settings
vim()
{
    local ret STTYOPTS="$(stty -g)"
    stty -ixon
    command vim "$@"
    ret=$?
    stty "$STTYOPTS"
    return "$ret"
}

# zsh
vim() STTY=-ixon command vim "$@"
