禁用/开启 GNOME “最近的文档”功能
使用 inkscape 将位图转化为矢量图用的是 GNOME 桌面，如果不希望他人看到你最近都看了哪些“机密”文档，也许你会想方设法地关闭 GNOME 好意为用户默认开启的“最近的文档 (Recent Document)”功能，本文会告诉你几个常用的小伎俩。
要禁用 GNOME 菜单中的“最近的文档”功能，可以这样做：
$ echo "" > $HOME/.recently-used.xbel
$ chmod 400 $HOME/.recently-used.xbel
$ chmod 400 $HOME/.recently-used.xbel
要是将来反悔，想再开启这一功能，可：
$ chmod 600 $HOME/.recently-used.xbel
利用 Linux 文件系统的小缺陷也可以实现关闭“最近的文档”功能，譬如：
$ rm $HOME/.recently-used.xbel
$ mkdir $HOME/.recently-used.xbel
$ mkdir $HOME/.recently-used.xbel
还可以利用 Nautilus 的脚本 (Script) 功能让上述关闭和启用“最近的文档”更“易用”一些，只需将下述 Bash 脚本：
#!/bin/sh
# Enable/Disable Recent Documents Menu in Gnome
if [ ! -f "$HOME/.recently-used" ]; then
echo "" > "$HOME/.recently-used.xbel"
chmod 600 "$HOME/.recently-used.xbel"
fi
if [ -w "$HOME/.recently-used.xbel" ]; then
echo "" > "$HOME/.recently-used.xbel"
chmod 400 "$HOME/.recently-used.xbel"
if [ "$?" = "0" ]; then
zenity --title="Disabled" --info --text="The 'Recent Documents' menu item has been disabled."
else
zenity --title="Error" --error --text="There was an error disabling the 'Recent Documents' menu."
fi
elif [ -f "$HOME/.recently-used.xbel" ]; then
chmod 600 "$HOME/.recently-used.xbel"
if [ "$?" = "0" ]; then
zenity --title="Enabled" --info --text="The 'Recent Documents' menu item has been enabled."
else
zenity --title="Error" --error --text="There was an error enabling the 'Recent Documents' menu."
fi
else
zenity --title="Error" --error --text="It appears the file '$HOME/.recently-used.xbel' does not exist and could not be created."
fi
# Enable/Disable Recent Documents Menu in Gnome
if [ ! -f "$HOME/.recently-used" ]; then
echo "" > "$HOME/.recently-used.xbel"
chmod 600 "$HOME/.recently-used.xbel"
fi
if [ -w "$HOME/.recently-used.xbel" ]; then
echo "" > "$HOME/.recently-used.xbel"
chmod 400 "$HOME/.recently-used.xbel"
if [ "$?" = "0" ]; then
zenity --title="Disabled" --info --text="The 'Recent Documents' menu item has been disabled."
else
zenity --title="Error" --error --text="There was an error disabling the 'Recent Documents' menu."
fi
elif [ -f "$HOME/.recently-used.xbel" ]; then
chmod 600 "$HOME/.recently-used.xbel"
if [ "$?" = "0" ]; then
zenity --title="Enabled" --info --text="The 'Recent Documents' menu item has been enabled."
else
zenity --title="Error" --error --text="There was an error enabling the 'Recent Documents' menu."
fi
else
zenity --title="Error" --error --text="It appears the file '$HOME/.recently-used.xbel' does not exist and could not be created."
fi
保存到 $HOME/.gnome2/nautilus-scripts 目录，假设保存为 recent-doc 文件，并将其属性设置为：
$ chmod 755 recent-doc
这样就可以在 Nautilus 中用鼠标右键菜单，在脚本菜单项中打开上述脚本，进行“最近的文档”功能的开启与关闭的设定。
