Linuxfind removes error messages

When Linux looks for it, access to certain directories may not be accessible and cannot be accessed. Many error messages are printed

1. The contents of the root directory file

-bash-3.2 $ ls anaconda-ks.cfg bea Desktop lib wls1036_generic.jar

2, find the file ending with .log,

-bash-3.2$ find . -name "*.log" find : ./.gconfd: ? ƒé™ ?? ?¤Ÿ find: ./.gnome2: ? ƒé™ ?? ?¤Ÿ find: ./.gnome2_private: ? &fnof ;é™ ?? ?¤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: ? ƒ é™ ?? ?¤Ÿ find: ./.metacit y: ? ƒé™ ?? ?¤Ÿ find: ./.gconf: ? ƒé™ ?? ?¤Ÿ find: ./.nautilus/metafiles: ? ƒé ;™ ?? ?¤Ÿ

At this time, the system language is in Chinese, but it is very strange. -bash-3.2$ echo $LANG zh_CN.UTF-8

English

-bash-3.2$ export LANG="en_US.UTF-8" -bash-3.2$ echo $LANG en_US.UTF-8

Then look for -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. Output error to /dev/null device, error message disappears -bash-3.2$ find . -name "*.log" 2>/dev/null -bash-3.2$ find . -name "*.cfg" 2>/dev/null ./anaconda-ks.cfg< Br>
