Linuxfind去除错误消息

当Linux 进行查找时，对某些目录的访问可能没有权限而无法进行访问，打印出很多错误消息
 
1、root目录文件内容
 
-bash-3.2$ ls
 anaconda-ks.cfg bea Desktop lib wls1036_generic.jar
 
2、查找.log结尾的文件，
 
-bash-3.2$ find . -name "*.log"
 find: ./.gconfd: ???é??????¤?
 find: ./.gnome2: ???é??????¤?
 find: ./.gnome2_private: ???é??????¤?
 find: ./.Trash: ???é??????¤?
 find: ./.java: ???é??????¤?
 find: ./.tuscany: ???é??????¤?
 find: ./.eggcups: ???é??????¤?
 find: ./.chewing: ???é??????¤?
 find: ./.mozilla/firefox: ???é??????¤?
 find: ./.scim: ???é??????¤?
 find: ./.metacity: ???é??????¤?
 find: ./.gconf: ???é??????¤?
 find: ./.nautilus/metafiles: ???é??????¤?
 
这时系统语言使用中文反而有问题，很奇怪
 -bash-3.2$ echo $LANG
 zh_CN.UTF-8
 
临时改为英文
 
-bash-3.2$ export LANG="en_US.UTF-8"
 -bash-3.2$ echo $LANG
 en_US.UTF-8
 
然后再查找
 -bash-3.2$ find . -name "*.log"
 find: ./.gconfd: Permission denied
 find: ./.gnome2: Permission denied
 find: ./.gnome2_private: Permission denied
 find: ./.Trash: Permission denied
 find: ./.java: Permission denied
 find: ./.tuscany: Permission denied
 find: ./.eggcups: Permission denied
 find: ./.chewing: Permission denied
 find: ./.mozilla/firefox: Permission denied
 find: ./.scim: Permission denied
 find: ./.metacity: Permission denied
 find: ./.gconf: Permission denied
 find: ./.nautilus/metafiles: Permission denied
 
3、将错误输出到/dev/null装置上，错误信息消失
 -bash-3.2$ find . -name "*.log" 2>/dev/null
 -bash-3.2$ find . -name "*.cfg" 2>/dev/null
 ./anaconda-ks.cfg
