學習shell有一段時間了，一直沒有機會練手，看到同事發了一張**，控制台顯示了當月的日曆，是用python實現的，感覺挺好玩，所以準備用shell來實現乙個，搞了一下午，終於搞定。
列印本月的日期
#! /bin/bash
#設定字型顏色
tiffcolor="\033[0;35m"
menucolor="\033[0;33m"
todaycolor="\033[0;35;44m"
start="\033[0m"
#計算各個日期
month=`date +%m`
day=`date +%d`
year=`date +%y`
weekday=`date -d "$year-$month-01" +%w`
nextmonth=`expr $month + 1`
today=`date +%d`
#計算本月有多少天
differ=$(( ($(date -d "$year-$nextmonth-01" +%s) - $(date +%s))/(24*60*60) ))
days=`expr $differ + $day`
#列印標題
echo -en "$"
echo -en "\t $year $month\n"
echo "sun mon tue wen thu fri sat"
echo -en "$"
#列印空格
if [ $weekday -ne 0 ];then
for((i=1;i<=$weekday;i++))
do echo -n " "
echo -n " "
done
fi#列印日期
for((i=1;i<=$days;i++))
do printf "%s" " "
echo -en "$"
#今天高亮顯示
if [ $today -eq $i ];then
echo -en "$"
fiprintf "%2d" $i
echo -en "$"
echo -en " "
if [ $((($weekday+$i)%7)) == 0 ];then
echo ""
fi# printf "%3d " $i
done
echo ""
執行結果：
