auto mount NAS direct on /home/

最近因為需要處理NAS 上的資料 , 每天早上開機都要 mount 一次 , 麻煩 , 寫一個 shell 來自動 mount 吧 !!

開機完畢後只要執行這個 shell 就會將需要的 mount 好. 預設值是 Public & Software 資料夾 , mount 位置在 /home/${USER}/NAS/ , 並且會自動建立對應位置 , 如果需要額外資料夾 , 可以 使用 nas_mount.sh abc 的方式.
這個 shell 會檢查 NAS 是否在線上 (ping IP) .
也會自動檢查是否已經 mount 好了.

內容如下:


#!/bin/sh
#
# vi:set ts=4:

## ===== defind echo color
COLOR_ECHO="echo -e"        ## in Fedora the color echo need have -e argument.
COLOR_NORMAL="\033[0m"
COLOR_BOLD="\033[1m"
COLOR_RED="\033[31m"
COLOR_GREEN="\033[32m"
COLOR_YELLOW="\033[33m"
COLOR_BLUE="\033[34m"
