打印本月的日期
#! /bin/bash#设置字体颜色tiffcolor="\033[0;35m"menucolor="\033[0;33m"todaycolor="\033[0;35;44m"start="\033[0m"#计算各个日期month=`date +%m`day=`date +%d`year=`date +%Y`weekday=`date -d "$year-$month-01" +%w`nextmonth=`expr $month + 1`today=`date +%d`#计算本月有多少天differ=$(( ($(date -d "$year-$nextmonth-01" +%s) - $(date +%s))/(24*60*60) )) days=`expr $differ + $day`#打印标题echo -en "${menucolor}"echo -en "\t $year $month\n"echo "SUN MON TUE WEN THU FRI SAT"echo -en "${start}"#打印空格if [ $weekday -ne 0 ];thenfor((i=1;i<=$weekday;i++))do echo -n " " echo -n " "donefi#打印日期for((i=1;i<=$days;i++))do printf "%s" " " echo -en "${tiffcolor}" #今天高亮显示 if [ $today -eq $i ];then echo -en "${todaycolor}" fi printf "%2d" $i echo -en "${start}" echo -en " " if [ $((($weekday+$i)%7)) == 0 ];then echo "" fi# printf "%3d " $idoneecho ""执行结果：
扩展：给定任意日期，打印当月的日期
