How to get date 2 days ago

Victor Semaska_3 — Tue, 05 Jun 2007 09:03:42 GMT

Greetings,

I'm primarily Tru64 UNIX but I'm slowly moving into the Linux world. I'm porting a ksh script of mine to Linux which gets the date 2 days ago. On Tru64 UNIX this command works:

# (export TZ; TZ=UTC+48; date '+%Y%m%d')
20070603

On RedHat Linux it returns yesterday's date:
# (export TZ; TZ=UTC+48; date '+%Y%m%d')
20070604

So, what am I doing wrong here.

Thanks,
Vic

In linux, you can use:

date --date "2 days ago"

Cool isn't it?

Thanks Ivan,

1) Somehow I knew you would have the answer.
2) I can't believe it's that simple.
