LinuxShell使用Bash脚本批量删除文件

　　PHP每天生成一个存有系统要删除的临时文件的.out文件列表，由bash脚本逐行通过读取.out文件（每一行代表一个待删除的文件）挨个删除，代码如下（dl.sh）：

　　#!/bin/bash

　　# Shell script utility to delete file.

　　# You can call script as follows, to read myfile.txt:

　　# ./dl.sh or.txt

　　#User define Fuction(UDF)

　　processLine(){

　　line="$@" #get all args

　　if [ ! -f $FILE ]; then

　　echo "$line does not exists"

　　else

　　echo "$line"

　　rm -rf $line

　　fi

　　}

　　#echo Please enter the file name:

　　#read FILE

　　if [ ! "$1" == "" ]; then

　　FILE="$1"

　　else

　　echo Please enter the file name:

　　read FILE

　　fi

　　if [ ! -f $FILE ]; then

　　echo "$FILE does not exists"

　　exit 1

　　elif [ ! -r $FILE ]; then

　　echo "$FILE cann't read"

　　fi

　　#read $FILE using the file descriptors

　　BAKIFS=$IFS

　　IFS=$(echo -en "\n\b")

　　exec 3<&0

　　exec 0<"$FILE"

　　while read -r line

　　do

　　processLine $line

　　done

　　exec 0<&3

　　IFS=$BAKIFS

　　exit 0

　　执行：

　　kokkowon@itbeing.com [~/www]# ./dl.sh ./temp.out

　　结果：
