以前用Windows的时候，我是说用XP的时候，因为不支持颜色主题，也无从知晓如何通过自动化的方式更换Windows的主题，所以，经常是人肉地每天换主题（其实只是为了换标题栏的颜色），追求新鲜感。 现在用Gnome桌面以后依然保持着这种爱好。遗憾是之前一直没有找到设置存放的位置。前两天在command-line-fu上恰好看到一个变换桌面背景的命令，原来这类配置都存放在gconf里，用gconftool就可以进行操作了。 然后很容易地就能在图形化配置管理器里找到颜色配置的键值位于/desktop/gnome/interface/gtk_color_scheme，值是一个用换行符隔开的名值对，内容就是我们在Appearance配置窗口里看到的那些。good，写个shell小程序每天换颜色！ 以下是我孱弱的shell脚本： [codesyntax lang="bash" lines="fancy"] case `date +%w` in 0) color=’#C4C4A0A00000′;; 1) color=’#CECE5C5C0000′;; 2) color=’#8F8F59590202′;; 3) color=’#4E4E9A9A0606′;; 4) color=’#20204A4A8787′;; 5) color=’#5C5C35356666′;; 6) color=’#A4A400000000′;; esac sedcommand=”s/\(selected_bg_color:\)\(.*\)/\1$color/” color_scheme=`gconftool-2 -g /desktop/gnome/interface/gtk_color_scheme | sed $sedcommand` gconftool-2 -t string -s /desktop/gnome/interface/gtk_color_scheme “$color_scheme” [/codesyntax] 每天一换，颜色是tango调色板里的色彩，HOHOHAHA
