标题: Linux下快速查找大文件或目录

如何查找大文件显示超过100M的文件

[root@strong ~]# cd /u01

[root@strong u01]# pwd

/u01

[root@strong u01]# find . -type f-size +100M

./app/oracle/oradata/YADATA/system01.dbf

./app/oracle/oradata/YADATA/example01.dbf

./app/oracle/oradata/YADATA/undotbs01.dbf

./app/oracle/oradata/YADATA/sysaux01.dbf

./app/oracle/product/11.2.0/db_1/lib/libserver11.a

./app/oracle/product/11.2.0/db_1/bin/oracle

./app/oracle/product/11.2.0/db_1/assistants/dbca/templates/Seed_Database.dfb

./app/oracle/product/11.2.0/db_1/javavm/admin/classes.bin

[root@strong u01]#

显示文件具体的属性或信息

[root@strong u01]# find . -type f -size+100M -print0 | xargs -0 ls -l

[root@strong u01]#

显示查找出来文件的具体大小

[root@strongu01]# find . -type f -size +100M -print0| xargs -0 du -h

901M ./app/oracle/oradata/YADATA/system01.dbf

346M ./app/oracle/oradata/YADATA/example01.dbf

121M ./app/oracle/oradata/YADATA/undotbs01.dbf

551M ./app/oracle/oradata/YADATA/sysaux01.dbf

147M ./app/oracle/product/11.2.0/db_1/lib/libserver11.a

190M ./app/oracle/product/11.2.0/db_1/bin/oracle

263M ./app/oracle/product/11.2.0/db_1/assistants/dbca/templates/Seed_Database.dfb

120M ./app/oracle/product/11.2.0/db_1/javavm/admin/classes.bin

sort命令进行大小排序

[root@strong u01]# find . -type f -size+100M -print0 | xargs -0 du -h | sort –nr （从大往小排序）

901M ./app/oracle/oradata/YADATA/system01.dbf

346M ./app/oracle/oradata/YADATA/example01.dbf

121M ./app/oracle/oradata/YADATA/undotbs01.dbf

120M ./app/oracle/product/11.2.0/db_1/javavm/admin/classes.bin

[root@strong u01]#

[root@strongu01]# find . -type f -size +100M -print0| xargs -0 du -hm | sort –n （从小往大排序）

120 ./app/oracle/product/11.2.0/db_1/javavm/admin/classes.bin

121 ./app/oracle/oradata/YADATA/undotbs01.dbf

147 ./app/oracle/product/11.2.0/db_1/lib/libserver11.a

如何查找Linux下的大目录Du –h进行查找

[root@strong ~]# cd /u01/app/

[root@strong app]# pwd

/u01/app

[root@strong app]# du -h--max-depth=1

2.8M ./oraInventory

6.9G ./oracle

6.9G .

调节depth的值，显示子目录的层级也会发生变化
