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
|
1 2 3 4 |
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
|
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
1）登录用户名，默认是demo
|
1 |
USERNAME="demo" |
2) 登录密码，默认是demo
|
1 |
PASSWORD="domo" |
3) transmission下载目录，默认在/root/Downloads
|
1 |
DLDIR=/root/Downloads |
4) 磁盘最大使用阀值，默认95%
|
1 |
DISK_USED_MAX="90" |
5) 日志存放路径，默认在/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。
|
1 |
DATA_TIME=$(date +"%y-%m-%d %H:%M:%S") |
