simple date query in ksh

[Sambo8]

Hi There,

I'm very new to ksh I have a script that goes into a folder that begins with a date and creates a file as follows:

#!/usr/bin/ksh
cd /work/sam/$(date +%Y%m%d)
touch hello.txt

this works to create a file called hello.txt in the path /work/sam/20080508/

now I want that to be minus 3 days? I've tried -3 and - %d3 with no joy - please can anyone help?

Cheers,
Sam

Hi

If you have GNU [tt]date[/tt], use the -d ( --date=DATE ) switch :

date -d '-3 days' +%Y%m%d

[gray]# or[/gray]

date -d '3 days ago' +%Y%m%d

Otherwise see faq822-4802.

If you don't have the GNU date then there's a really good date function written by PHV at faq80-4800

Hi

Why is that FAQ better than the FAQ I suggested ?

PHV put that FAQ in both the "UNIX scripting" and the "-General UNIX discussion" forum. So it is basically the same info in two separate locations.
