查找当前目录下的大于1M的文件的各种实现

感谢小云同学，兰兰同学，以及其他同学的交流

使用find的参数实现

1. [root@T-bagwell mnt]# find . -maxdepth 1 -size +1000000c
2. ./sys.tar.gz
3. ./install.tar.bz2
4. ./CTeX_2.9.0.152_Full.exe
5. ./php-5.3.6.tar.gz
6. [root@T-bagwell mnt]# ls -lh
7. total 1.3G
8. -rw-r--r-- 1 root root 1.1G 2011-04-28 11:35 CTeX_2.9.0.152_Full.exe

11. drwxrwxrwx 8 flash games 4.0K 2011-04-24 06:38 libevent-1.4.12-stable

24. -rw-r--r-- 1 root root 19M 2009-07-13 22:38 sys.tar.gz
25. [root@T-bagwell mnt]#

使用ls+awk组合管道

1. [root@T-bagwell mnt]# find . -maxdepth 1 -size +1000000c;
2. ./sys.tar.gz
3. ./install.tar.bz2
4. ./CTeX_2.9.0.152_Full.exe
5. ./php-5.3.6.tar.gz
6. [root@T-bagwell mnt]# ls -l .|awk '{if($5>1000000) print R$8}'
7. CTeX_2.9.0.152_Full.exe
8. install.tar.bz2
9. php-5.3.6.tar.gz
10. sys.tar.gz
11. [root@T-bagwell mnt]#

使用find+ll+awk组合（管道）

1. [root@T-bagwell mnt]# find ./ -name "*" -maxdepth 0 -exec ls -l {} \;|awk '{if($5>1000000) print $8}'
2. CTeX_2.9.0.152_Full.exe
3. install.tar.bz2
4. php-5.3.6.tar.gz
5. sys.tar.gz
6. [root@T-bagwell mnt]#
7. [root@T-bagwell mnt]# find . -maxdepth 1 -size +1000000c;
8. ./sys.tar.gz
9. ./install.tar.bz2
10. ./CTeX_2.9.0.152_Full.exe
11. ./php-5.3.6.tar.gz
12. [root@T-bagwell mnt]#
