在Windows系统中我们可以使用TreeSize工具查找一些大文件或文件夹非常的方便高效在Linux系统中如何去搜索一些比较大的文件呢下面我整理了一下在Linux系统中如何查找大文件或文件夹的方法。 1 如何查找大文件 其实很多时候你需要了解当前系统下有哪些大文件比如文件大小超过100M或1G阀值视具体情况而定。那么如何把这些大文件搜索出来呢例如我要搜索当前目录下超过800M大小的文件 [rootgetlnx01 u03]# pwd /u03 [rootgetlnx01 u03]# find . -type f -size 800M ./flash_recovery_area/backup/backupsets/ora_df873519197_s46815_s1 ./flash_recovery_area/backup/backupsets/ora_df873523646_s46822_s1 ./flash_recovery_area/backup/backupsets/ora_df873521714_s46818_s1 ./flash_recovery_area/backup/backupsets/ora_df873522876_s46820_s1 ./flash_recovery_area/backup/backupsets/ora_df873517396_s46813_s1 ./flash_recovery_area/backup/backupsets/ora_df873523321_s46821_s1 ./flash_recovery_area/backup/backupsets/ora_df873515765_s46811_s1 ./flash_recovery_area/backup/backupsets/ora_df873520789_s46817_s1 ./flash_recovery_area/backup/backupsets/ora_df873524162_s46823_s1 ./flash_recovery_area/backup/backupsets/ora_df873518302_s46814_s1 ./flash_recovery_area/backup/backupsets/ora_df873519953_s46816_s1 ./flash_recovery_area/backup/backupsets/ora_df873516500_s46812_s1 ./flash_recovery_area/backup/backupsets/ora_df873513413_s46809_s1

./oradata/epps/gmtinv_d07.dbf ./oradata/epps/undotbs01.dbf ./oradata/epps/gmtinv_x02.dbf 如上命令所示我们仅仅能看到超过800M大小的文件的文件名称但是对文件的信息例如文件大小、文件属性一无所知那么能否更详细显示一些文件属性或信息呢当然可以如下所示 [rootgetlnx01 u03]# find . -type f -size 800M -print0 | xargs -0 ls -l -rw-r----- 1 oracle oinstall 2782846976 Mar 6 11:51 ./flash_recovery_area/backup/backupsets/ora_df873513413_s46809_s1 -rw-r----- 1 oracle oinstall

./flash_recovery_area/backup/backupsets/ora_df873523321_s46821_s1 不过如上截图所示有时候排列的顺序并不完全是按大小一致这个是因为du命令的参数h所致你可以统一使用使用MB来显示这样就能解决这个问题。到这里这个在Linux系统查找大文件的命令已经非常完美了当然如果你还有很多的需求那么可以在这个命令上做修改、调整. 2: 如何查找Linux下的大目录 譬如有时候磁盘空间告警了而你平时又疏于管理、监控文件的增长那么我需要快速的了解哪些目录变得比较大那么此时我们可以借助du命令来帮我们解决这个问题。 [rootgetlnx01 u03]# du -h --max-depth1 16K ./lostfound 33G ./flash_recovery_area 37G ./oradata 70G . 如果你想知道flash_recovery_area目录下面有哪些大文件夹那么可以将参数max-depth2 如果你想对搜索出来的结果进行排序那么可以借助于sort命令。如下所示 [rootgetlnx01 u03]# du -h --max-depth2 | sort -n 3.5G ./flash_recovery_area/EPPS 16K ./lostfound 29G ./flash_recovery_area/backup 33G ./flash_recovery_area 37G ./oradata 37G ./oradata/epps 70G . [rootgetlnx01 u03]# du -hm --max-depth2 | sort -n 1 ./lostfound 3527 ./flash_recovery_area/EPPS 29544 ./flash_recovery_area/backup 33070 ./flash_recovery_area 37705 ./oradata 37705 ./oradata/epps 70775 . [rootgetlnx01 u03]# cd / [rootgetlnx01 /]# du -hm --max-depth2 | sort -n 有时候搜索出来的结果太多了譬如我从根目录开始搜索一直在刷屏如果我只想查出最大的12个文件夹怎么办呢此时就要借助head命令来显示了 [rootgetlnx01 /]# du -hm --max-depth2 | sort -nr | head -12 407480 . 167880 ./u04 158685 ./u02/oradata 158685 ./u02 152118 ./u04/oradata 70775 ./u03 37705 ./u03/oradata 33070 ./u03/flash_recovery_area 5995 ./u01/app 5995 ./u01 3551 ./usr 1558 ./usr/share [rootgetlnx01 /]#
