FILECLEANER

命令行文件去重工具

编写这个工具的初衷在于给fastdfs小文件进行去重 并发的读写操作文件,目前默认goroutine最大数量为10,如需修改,只需要修改model包对应的channel数量


  • 命令行参数
> -c bool  是否启用级联去重操作(默认 false)
> -p string  去重操作的目录 (默认路径 /home/fastdfs/storage/data)  
> -dm string  删除的方式,目前支持3种参数(默认 ln):
              -dm="dry" 只模拟查看重复文件和执行效果,不真实执行删除操作
              -dm="rm" 直接删除重复文件; 
              -dm="ln" 删除重复文件,并且以第一个文件为源目标,创建其他文件的硬链接
> -n int   并发执行的线程数,最低1,最高10(默认 4)
> -ctime bool 是否按文件创建时间去重
> -mtime bool 是否按文件修改时间去重
> -atime bool 是否按文件访问时间去重
> -t string  时间点,例如:
        +n  n+1天前
         n  n+1天前到n天前的时间段
        -n  n天前至今  
  • 示例
# 级联清理文件
> filecleaner -c=true -p="/home/data"

# 按文件创建时间清理,清理10天前的
> filecleaner -c=true -p="/home/data" -ctime -t=+9

# 只模拟查看清理效果,不实际删除文件
> filecleaner -c=true -p="/home/data" -dm="dry"
