Is there support for "man date" under z/OS UNIX? Paul indicated that
the double-hypen parms are non-POSIX and therefore not supported under
z/OS; but "man date" under Fedora also shows "-d" as an alternative for
"--date=", so for example under Fedora it's also possible to use
date +%Y%m%d -d"1 day ago"
or
date +%Y%m%d -d"yesterday"
Maybe that form is supported?
P.S. I interpreted your original post as saying you had tried
date +%Y%m%d "yesterday"
where apparently you had intended to imply
date +%Y%m%d --date="yesterday"

Thank you for all your hints and tips but I need just one command without an additional script or
similar since I need this for different customers. All that I want is just create a file with some
content and give that file "yesterdays" date. In each other Unix version not a problem at
all, but USS seems to be different. The "date...--date" syntax is invalid in USS. As I
said in my first post, I tried nearly everything I believe.....
HELP :-)

Betreff: Re: AW: USS "date" command, subtract one day
Correct. So if you really want something that will work for all dates,
including first of month, first of month in March on leap and nonleap year,
first of year, etc. you need something else.
I'm not enough of a UNIX authority to know if this is standard for all implementations of the UNIX date command and
can't test in z/OS environment, but a search for "relative dates" and "Linux" found a
"--date" parameter for the "date" command. At least on Fedora Linux the date command already
appears to have relative date calculation built in.
Currently (2013-03-14) on Fedora the command date --date="14 days ago"
returns "Thu Feb 28 09:52:21 CST 2013"
and
date --date="379 days ago"
returns "Wed Feb 29 09:57:26 CST 2012"
If "date" under z/OZ UNIX supports the same parameters, then date +%Y%m%d --date="1
day ago"
which today on Fedora returns "20130313" may be the form you need.

Thx perfect, thats exactly what I need. But I'm afraid this doesn’t work for
the first of a month for example 20130401 will then be 20130400 or I'm wrong?

Maybe something like that, will help you:
echo "`date +%Y%m%d` - 1" | bc

Hi,
I dont know if this is the right forum but I hope someone could help
anyway. I want to subtract "one day" from the actual date with one
USS unix command.
The actual date I get via "date +%Y%m%d" (for example 20130314), but
"date +%Y%m%d-1" or "...yesterday" don’t work. I have tried
everything without success. Does anybody have a tip for me? It must
be achieved within one command not more.
Thx
Uwe
