Transmission 自动删除脚本 RSS永不爆盘

备份自https://blog.wangyan.org/bt-shell-transmission-clean/

Transmission 一、删除顺序

首先逐个删除已经下载完的任务，一旦满足条件则停止删除
接着逐个删除已经暂停的任务，一旦满足条件则停止删除
最后按顺序删除正在下载的任务（相当于删除全部任务），直到满足条件。
如果还是未能满足条件，则动用”rm -rf”强制删除下载目录内的所有文件。

二、使用方法

2.1、创建脚本并测试

mkdir ~/trans/ && cd ~/trans/
新建脚本：nano trans_cleanup.sh
运行权限：chmod +x ./trans_cleanup.sh
./trans_cleanup.sh #先运行一次查看是否正常工作

mkdir ~/trans/ && cd ~/trans/

新建脚本：nano trans_cleanup.sh

运行权限：chmod +x ./trans_cleanup.sh

./trans_cleanup.sh #先运行一次查看是否正常工作

trans_cleanup.sh脚本：

2.2、设置cron计划任务

自动检查频率可随意设置，例如每5分钟检查一次

crontab -e
*/5 * * * *  /bin/bash  /root/trans/trans_cleanup.sh

1 2	crontab -e /5 * * * /bin/bash /root/trans/trans_cleanup.sh

三、配置选项

用编辑器打开trans_cleanup.sh文件，自定义以下选项

trans_cleanup

1）登录用户名，默认是demo

USERNAME="demo"

1	USERNAME="demo"

2) 登录密码，默认是demo

PASSWORD="domo"

1	PASSWORD="domo"

3) transmission下载目录，默认在/root/Downloads

DLDIR=/root/Downloads

1	DLDIR=/root/Downloads

4) 磁盘最大使用阀值，默认95%

DISK_USED_MAX="90"

1	DISK_USED_MAX="90"

5) 日志存放路径，默认在/var/log/trans_cleanup.log

LOG_PATH="/var/log/trans_cleanup.log"

1	LOG_PATH="/var/log/trans_cleanup.log"

6) 日志日期格式，一般不需要改。

DATA_TIME=$(date +"%y-%m-%d %H:%M:%S")

1	DATA_TIME=$(date +"%y-%m-%d %H:%M:%S")
