Data Unix Date query

Hi there,

I am trying to do the following in Unix (Solaris 2.7):

1...Find the actual date 7 days ago in format (dd-mmm-yyyy) and with the weekday prefably,

2...Find the date 5 days after the above in the same format.

How can I do this in Unix instead of accessing our Oracle database and doing the date formatting in Oracle instead?

Many thanks for your help,

Hi there,

Thanks for your email. I thought my original email was pretty clear? Ok anyway, what I would do in unix to get today's date usually I use for filenames, or report headings etc:

echo "`date + %d%m%Y`"

No what would be helpful for me would be to get the date in the above format 7 days ago or however many days I specify to go back or forward.

Can you help?

Many thanks,

You could use a script executing this line from CRON everyday.

date > /tmp/date.[1-99]


date > /tmp/date.`date`

I am still puzzled as to why you need the date from several days ago.

I have posted several scripts showing how to do date arithmetic in ksh. Use the search function.

I found this from one of the moderators responses to Perderabo.

Not mine but very good!

perl -e 'print scalar localtime(time-86400)'. Gives output of yesterday 24 hours ago.

Just change the 86400 by multiples to go back X number of days.
