Close all vim buffers with files under a path

close_matching_vim_buffers

Your vim needs to be compiled with clientserver support. You can check:

  vim --version|grep +clientserver

Set up an alias so regular vim starts with a server (add it to your shell aliases):

  alias vim='vim --servername "VIM"'

close_vim_buf.sh

#!/bin/bash
help="Closes all vim buffers with files under given path.\n\
Modified buffer contents will be written out."

if [ $# -eq 0 ]
then
    echo -e "$help"
    echo "Usage: $0 PATH"
    exit
fi

close_path="$1"
abs_path=$(readlink -f "$close_path")

expand_tilde()
{
    case "$1" in
    (\~)        echo "$HOME";;
    (\~/*)      echo "$HOME/${1#\~/}";;
    (\~[^/]*/*) local user=$(eval echo ${1%%/*})
                echo "$user/${1#*/}";;
    (\~[^/]*)   eval echo ${1};;
    (*)         echo "$1";;
    esac
}
