Add into some xinitrc scripts..
=================================
#Wallpaper shifts between day and night
HOUR=`env LANG="en_US.UTF-8" date|cut -d" " -f4|cut -d":" -f1`
SHIFT=0
WALL="/Share/Walls/day.jpg"
if [ $HOUR -lt 6 ]
then
SHIFT=1
fi
if [ $HOUR -ge 19 ]
then
SHIFT=1
fi
if [ $SHIFT -eq 1 ]
then
WALL="/Share/Walls/night.jpg"
fi
Esetroot -fit $WALL &
==========================
还可以增加SHIFT的值和时间判断设置周末日夜的不同背景

有意思...

#!/bin/sh
#Wallpaper shifts between day and night and appears over differences on weekend
TIME=`env LANG="en_US.UTF-8" date`
day_night ()
{
shift=0
if [ $1 -lt 6 ]
then
shift=1
fi
if [ $1 -ge 19 ]
then
shift=1
fi
echo $shift
}
day_week ()
{
shift=0
if [ $1 == "Fri" ]
then
shift=1
fi
if [ $1 == "Sat" ]
then
shift=2
fi
if [ $1 == "Sun" ]
then
shift=3
fi
echo $shift
}
WALL_DAY="/Share/Walls/TobagoCays.jpg"
WALL_NIGHT="/Share/Walls/marstwins.jpg"
WALL_WEEK_DAY="/Share/Walls/beach.jpg"
WALL_WEEK_NIGHT="/Share/Walls/Sealife.jpg"
WALL=
SHIFT_DAY=$(day_night `echo $TIME|cut -d" " -f4|cut -d":" -f1`)
SHIFT_WEEK=$(day_week `echo $TIME|cut -d" " -f1`)
if [ $SHIFT_WEEK -eq 0 ]
then
if [ $SHIFT_DAY -eq 0 ]
then
WALL=$WALL_DAY

WALL=$WALL_NIGHT
