获取时间

TIME_CURR=$(date "+%Y.%m.%d.%H.%M.%S")

shell第一行bash/dashh

#!/bin/bash

shell文件通用脚本

SCRIPT_FILE=${BASH_SOURCE[0]}
SCRIPT_DIR=${SCRIPT_FILE%/*}
SCRIPT_PATH=$(cd ${SCRIPT_DIR%/*} && pwd)
echo "---|SCRIPT_FILE      : ${SCRIPT_FILE}|---";
echo "---|SCRIPT_DIR       : ${SCRIPT_DIR}|---";
echo "---|SCRIPT_PATH      : ${SCRIPT_PATH}|---";

提取shell脚本文件名

$0 是命令行里面的执行文件 
${BASH_SOURCE[0]} 才是当前执行文件 

比如命令行执行 0.sh 然后 0.sh 里面 include 1.sh 
那么 1.sh 里面的 $0 对应的是 0.sh, ${BASH_SOURCE[0]} 才是 1.sh

box_echo "0=$0"
box_echo "BASH_SOURCE=${BASH_SOURCE}"
box_echo "BASH_SOURCE[0]=${BASH_SOURCE[0]}"
box_echo "BASH_SOURCE[1]=${BASH_SOURCE[1]}"

	done
	
	if [ ! -f ${WGET_DES_PATH}/${WGET_FILE} ]; then
