Linux find 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: ?ƒé™???¤Ÿ

find: ./.gnome2: ?ƒé™???¤Ÿ

find: ./.gnome2_private: ?ƒé™???¤Ÿ

find: ./.Trash: ?ƒé™???¤Ÿ

find: ./.java: ?ƒé™???¤Ÿ

find: ./.tuscany: ?ƒé™???¤Ÿ

find: ./.eggcups: ?ƒé™???¤Ÿ

find: ./.chewing: ?ƒé™???¤Ÿ

find: ./.mozilla/firefox: ?ƒé™???¤Ÿ

find: ./.scim: ?ƒé™???¤Ÿ

find: ./.metacity: ?ƒé™???¤Ÿ

find: ./.gconf: ?ƒé™???¤Ÿ

find: ./.nautilus/metafiles: ?ƒé™???¤Ÿ

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
