用wget循環獲取指定url下的文件

原由：爲了獲取某個國外網站的模板（國外的設計師真的很贊），嘗試靠wget抓取網頁。其中有部分圖片在js文件中標註，以下

;(function( $, window, document, undefined ) {
	
	var Customizer = function( ) {
		this.init();
	}

	Customizer.prototype = {

		patterns: [
			'assets/images/layout/bg/arches.png', 
			'assets/images/layout/bg/blu_stripes.png', 
			'assets/images/layout/bg/bright_squares.png', 
			'assets/images/layout/bg/brushed_alu.png', 
			'assets/images/layout/bg/circles.png', 
			'assets/images/layout/bg/climpek.png', 
			'assets/images/layout/bg/connect.png', 
			'assets/images/layout/bg/corrugation.png', 
			'assets/images/layout/bg/cubes.png', 
			'assets/images/layout/bg/diagonal-noise.png', 
			'assets/images/layout/bg/diagonal_striped_brick.png', 
			'assets/images/layout/bg/diamonds.png', 
			'assets/images/layout/bg/diamond_upholstery.png', 
			'assets/images/layout/bg/escheresque.png', 
			'assets/images/layout/bg/fabric_plaid.png', 
			'assets/images/layout/bg/furley_bg.png', 
			'assets/images/layout/bg/gplaypattern.png', 
			'assets/images/layout/bg/gradient_squares.png', 
			'assets/images/layout/bg/grey.png', 
......

我把中間變化的png文件名單獨列成一個文件（png.list），以下

escheresque.png 
fabric_plaid.png 
furley_bg.png 
gplaypattern.png 
gradient_squares.png 
grey.png 
grilled.png 
hexellence.png 
lghtmesh.png 
light_alu.png 
light_checkered_tiles.png 
light_honeycomb.png 
littleknobs.png 
nistri.png 
noise_lines.png 
noise_pattern_with_crosslines.png 
noisy_grid.png 
norwegian_rose.png 
pineapplecut.png 
......

向公司的一個運維大牛諮詢了一段shell腳本（downpng.sh），記錄一下，同時與你們分享，代碼以下：

#!/bin/bash
# Bash for download png file

text="png.list"
url="http://www.xxx.com/xxx/assets/images/layout/bg"
# ==============================================
# Function
# ==============================================
man {
while read line
	do
	echo -e "$line"
	wget -q $url/$line
done < $text
}

# ==============================================
# Action
# ==============================================
man

代碼很簡單，使用while read ，可是用非腳本語言寫就很繁瑣（偶是搞java的，尤爲如此），看來要好好學習一下bash了。
