这个貌似需要更新icon数据库。 # Update any existing icon cache files: if find /usr/share/icons 2> /dev/null | grep -q icon-theme.cache ; then for theme_dir in /usr/share/icons/* ; do if [ -r ${theme_dir}/icon-theme.cache ]; then echo "Updating icon-theme.cache in ${theme_dir}..." /usr/bin/gtk-update-icon-cache -t -f ${theme_dir} 1> /dev/null 2> /dev/null & fi done # This would be a large file and probably shouldn't be there. if [ -r /usr/share/icons/icon-theme.cache ]; then echo "Deleting icon-theme.cache in /usr/share/icons..." #/usr/bin/gtk-update-icon-cache -t -f /usr/share/icons 1> /dev/null 2> /dev/null & rm -f /usr/share/icons/icon-theme.cache fi fi
