How do I get the day of the week for tomorrow and the day after? For example, if today is Monday, how can I get “Tuesday” and “Wednesday”? I have weather data for day2 and day3 from getwthr.com (for GeekTool) but need the days of the week to apply it to.

Thanks.

@Balaswamy : easiest way to print months in alphabets format is using CASE

By: Vivek Gite

Vivek Gite — Sat, 28 Aug 2010 09:26:40 +0000

Tested with GNU date:

date +"%b"
date +"%b" --date="1 month ago"
for d in {1..6}; do date +"%b" --date="$d month ago"; done
man date

So I got this from a friend, how recommended to use perl:

CURR_DATE=`perl -e ‘use POSIX qw(strftime);$d = strftime “%m/%e/%Y %H:%M:%S”, localtime(time);print $d;’`
START_DATE=` perl -e ‘use POSIX qw(strftime);$d = strftime “%m/%e/%Y %H:%M:%S”, localtime(time() – 43200);print $d;’`
echo $CURR_DATE
echo $START_DATE

This works great!!

I should mentioned that I am using SunOS 5.10
As I have tried
E=$(date –date=’-12 hours’)
and it’s not working!

I get this error:
date: illegal option — date=-12 hours
usage: date [-u] mmddHHMM[[cc]yy][.SS]
date [-u] [+format]
date -a [-]sss[.fff]

Hi everyone!
This is a great document that covers most of my date/time issues :-)

However I am trying to cron a job that will execute my bash script, the challenge that I am facing is I need to run the script for the last 12 hours, here is what I have:

#!/usr/bin/bash
# Set the current local time in this format: ’03/18/2010 17:52:18′
CURR_DATE=`date +%m/%d/%Y” “%H:%M:%S`
#Set the start time (current time – 12 hours) <– This is where I am stuck!!!
START_DATE=`date +%m/%d/%Y" "%T`

How do set the start time to CURR_DATE -12 hours???

Thanks,
guy

I setup linux script to delete my backups older than few days:
RBRDAN=`date –date=”3 days ago” +%w`

rm /u02/oracle/backup/rman/$RBRDAN/*

But, I got error:
rm: cannot remove `/u02/oracle/backup/rman/6\r/*’: No such file or directory

For some reason, it gives me “\r” at the end of the day. Instead of “6″, it gives me “6\r”.
Does anybody know what is the problem.

Thanks.
