1、使用find的参数实现
[root@xiaobb mnt]# find . -maxdepth 1 -size +1000000c
./sys.tar.gz
./install.tar.bz2
./CTeX_2.9.0.152_Full.exe
./php-5.3.6.tar.gz
[root@xiaobb mnt]# ls -lh
total 1.3G
-rw-r--r-- 1 root root 1.1G 2011-04-28 11:35 CTeX_2.9.0.152_Full.exe
drwxr-xr-x 19 root root 12K 2011-04-24 20:28 git
-rw-r--r-- 1 root root 135M 2011-03-18 07:00 install.tar.bz2
drwxrwxrwx 8 flash games 4.0K 2011-04-24 06:38 libevent-1.4.12-stable

-rw-r--r-- 1 root root 19M 2009-07-13 22:38 sys.tar.gz
[root@xiaobb mnt]#
2、使用ls+awk组合管道
[root@xiaobb mnt]# find . -maxdepth 1 -size +1000000c;
./sys.tar.gz
./install.tar.bz2
./CTeX_2.9.0.152_Full.exe
./php-5.3.6.tar.gz
[root@xiaobb mnt]# ls -l .|awk '{if($5>1000000) print R$8}'
CTeX_2.9.0.152_Full.exe
install.tar.bz2
php-5.3.6.tar.gz
sys.tar.gz
[root@xiaobb mnt]#
3、使用find+ll+awk组合（管道）
[root@xiaobb mnt]# find ./ -name "*" -maxdepth 0 -exec ls -l {} ;|awk '{if($5>1000000) print $8}'
CTeX_2.9.0.152_Full.exe
install.tar.bz2
php-5.3.6.tar.gz
sys.tar.gz
[root@xiaobb mnt]#
[root@xiaobb mnt]# find . -maxdepth 1 -size +1000000c;
./sys.tar.gz
./install.tar.bz2
./CTeX_2.9.0.152_Full.exe
./php-5.3.6.tar.gz
