[SHELL we talk 之六] 下载完成后关机
最近天气热,Ubuntu下花了两次屏...常要下些东西,等它下完再关机,这个在WIN下用迅雷很简单。
但linux下的一些下载工具却没这功能...
我常用的命令是 wget ..
wget -b -c http://xxx.xxx.xxx/xxx
这样就会产生一个wget-log文件记录下载记录(如果wget-log已存在会后面加数字1,wget-log1存在则生成wget-log2,依此类推)
log文件的内容里有下载的百分比
要实现下载完毕关机我们只要用到两个命令:查看文件内容和关机
tail (因为log文件是追加形式生成的) 和 shutdown
#!/bin/sh
# @desciption:
# test weather the wget's log contains 100%
# if true then bell and exit
# else sleep some seconds for next test
#@useage:
# testDone ]
# log_file_name default for "~/downloads/wget-log
# wait_seconds default for 10 seconds
# @notice
# there's not any error detemin in this script
#
if [ $# -gt 0 ]
then
echo "you would like to test $1"
filename="$HOME/downloads/$1"
if [ $# -gt 1 ]
then
sleeptime=$2
else
sleeptime=10
fi
else
filename="$HOME/downloads/wget-log"
sleeptime=10
fi
#echo $filename
while [ "1" = "1" ]
do
tail$filename |grep "100%" >/dev/null
if [ $? != "1" ]
then
echo "done.. ...exiting...\c"
init 0 # or use shutdown
break
fi
#echo "not down..\n"
sleep$sleeptime
done
[ 本帖最后由 onttpi 于 2008-6-9 15:08 编辑 ] 代码呢?? 原本只是要做成完成就响铃,所以说明与代码有所不符... HJACK改成下载多个文件时全部下完再关机.. 忘了wget的log文件格式是怎么样的了。。
