About

disk-usage

快速诊断磁盘空间占用,定位大文件和可清理目录。

配置(首次)

无需配置。

常用命令

查看磁盘总览

df -h

查看当前目录各子目录大小

du -h --max-depth=1 . | sort -hr | head -20

查找指定路径下最大的 N 个文件

find  -type f -exec du -h {} + 2>/dev/null | sort -hr | head -

查找超过指定大小的文件

find  -type f -size +M -exec ls -lh {} + 2>/dev/null
# 示例:find /home -type f -size +100M

统计各文件类型占用

find  -type f | sed 's/.*\.//' | sort | uniq -c | sort -rn | head -20

查找可安全清理的缓存/临时文件

# 系统日志(超过7天)
find /var/log -type f -name "*.log" -mtime +7 -exec ls -lh {} +
# 用户缓存
du -h --max-depth=1 ~/.cache 2>/dev/null | sort -hr | head -10
# 临时文件
find /tmp -type f -atime +3 -exec ls -lh {} + 2>/dev/null

注意事项

  • du 在大目录上可能很慢,可加 --max-depth 限制层级
  • find-size 参数:+100M = 大于100MB,-1G = 小于1GB
  • 清理前确认文件用途,避免删除正在使用的日志或缓存
  • /tmp 清理注意检查是否有进程正在使用临时文件
