[root@localhost shell]# date  
Tue Jul  5 04:58:08 CST 2011
[root@localhost shell]# date    显示系统当前日期
Tue Jul  5 04:58:15 CST 2011
[root@localhost shell]# date 2011-07-06
date: invalid date `2011-07-06'
[root@localhost shell]# date -s 2011-07-06    修改当前日期
Wed Jul  6 00:00:00 CST 2011
[root@localhost shell]# date     显示修改后的日期
Wed Jul  6 00:00:02 CST 2011
[root@localhost shell]# date -d "+4 day"   显示4天后的日期
Sun Jul 10 00:00:27 CST 2011
[root@localhost shell]# date -d "+4 day" +%y%m%d   格式化显示
110710
[root@localhost shell]# date -d "+4 day" +%Y%m%d   格式化显示
20110710
[root@localhost shell]# date -d "-4 day" +%Y%m%d  4天前
20110702
[root@localhost shell]# date -d "yesterday" +%Y%m%d   显示昨天
20110705

[root@localhost shell]# date -d "tomorrow" +%Y%m%d   显示明天
20110707

[root@localhost shell]# date -d "2 days ago" +%Y%m%d   显示2天前
20110704

date -d "2010-10-18 02:05:45 3 days ago" +%Y-%m-%d" "%H:%M:%S

2010-10-15 02:05:45

date -d "2010-10-18 02:05:45 3 days" +%Y-%m-%d" "%H:%M:%S

example：

 

 #!/bin/sh

join -t'|' -a1 -o 1.2,1.4,1.3,1.5,1.8,1.9,1.10,1.11,1.15,1.22,1.23,1.24,1.27,2.4,2.5,2.6 -j1 23 -j2 2 /mnp/SEND/1/20110719/*.submit /mnp/SEND/1/20110719/*.rsp > css/text.css
split -1 css/text.css css/

todayDir=$(date +%Y%m%d)
for tailNumberDir in 0 1 2 3 4 5 6 7 8 9 ;do
AllDir=${Dir}${todayDir}'/'${tailNumberDir}'/'
echo $AllDir
done
dir='SEND/'${sendType}'/'
