date command question

lifetaster · 02-22-2004, 08:49 PM

date=`date -u +%m/%d/%Y`
echo "$date"

with the commands above, "02/23/2004" will be displayed.
how can I get "02/22/2004"?

thank you.

The "-u" option gives the date for the current UTC time, which is already tomorrow. Pull that out, and it should work.

thanks, but what i meant is this:

now with

date=`date -u +%m/%d/%Y`
echo "$date"

"02/22/2004" will be displayed.
how to get the string "02/21/2004"?

(date command will give me Mon Feb 23 11:06:04 SST 2004)
(date -u shows: Mon Feb 23 03:06:04 UTC 2004)

I guess your question isn't as clear to me as it is to you... Are you trying to get yesterday's date? You can put a describer into date...

Code:

$ date --date "yesterday" +%Y.%m.%d
2004.02.22
$ date --date "1 day ago" +%Y.%m.%d
2004.02.22
$ date --date "4 day ago" +%Y.%m.%d
2004.02.19
$ date --date "4 days ago" +%Y.%m.%d
2004.02.19
$ date --date "4 month ago" +%Y.%m.%d
2003.10.23
$ date --date "2 year ago" +%Y.%m.%d
2002.02.23
$ date --date "2 year" +%Y.%m.%d
2006.02.23
$ date --date "2 week" +%Y.%m.%d
2004.03.08

thanks for your information.

as tested, the commands given above seem only work in LINUX not in HP-UX
