2020年已经过去大半了,更新一下博客,刷一下存在感。

去年收了一个暴风影音播客云二期,安装了破解版的黑群晖。每三个月更新一次Let’s Encrypt证书。

但它的Android客户端很奇怪,每次更新证书之后就无法再登录了,需要把App缓存清掉,重新登录,导致的后果就是需要重新设置备份文件目录。然后就每次重新开始备份手机上的视频照片,关键不是增量的,需要全部重新备份。

ssh进入系统后就可以看到重复的文件,文件名加了后缀_1, 例如 VID_20200913_170932_1.mp4, 文件太多超过2W个, 不能手动去删除,于是顺手就写了一个脚本去自动删除。

原理很简单,先找到那些不含_1后缀的文件,然后查看是否存在_1后缀的文件,文件存在的话就直接删掉,310G变到202G了,清理了100G+的空间。

#!/bin/sh
count=0
remove=0
for file in `ls|grep -v "_1\." `
do
	((count++))
	#echo -n "${count} "
	name=`echo ${file}|cut -d "." -f1`
	ext=`echo ${file}|cut -d "." -f2`
	dup_file=${name}_1.${ext}
	echo -n  "total:${count}, remove:${remove}"
	if [ -f ${dup_file} ]; then
		#echo ${dup_file}
		((remove++))
		echo " rm ${dup_file}"
		rm ${dup_file}
	else
		echo ""
	fi
done

#echo "total:${count}, remove:${remove}"

运行效果如下

total:12308, remove:11144 rm VID_20200724_211814_1.mp4
total:12309, remove:11145 rm VID_20200724_212118_1.mp4
total:12310, remove:11146 rm VID_20200724_212337_1.mp4
