NO....

gnu date command has that option.

[Kevin Nikiforuk]

Thanks for the reply.

But I've heard HP supports some GNU commands. Any way to verify if the GNU date command is supported?

Cheers

The Gnu version is not supported by HP nor should it be; it is freely available from any of the HP-UX Porting Centre's so check the licensing and agreements there.

If you must use HP "supported" tools then use Perl. A combination of time() - 86400 + the localtime (or strftime) function will do anything the date command will do.

As you could also have read in http://mirrors.develooper.com/hpux/faq.html

* How do I print Yesterday?

d3:/ 102 > echo 'Yesterday'
Yesterday
d3:/ 103 > perl -le 'print scalar localtime time - 86400'

Or use A.Clay Stephenson's date hammer, which can also be used for more complicated actions from the command line, as will using the modules Date::Calc or Date::Manip with Perl.

A.Clay's valuable date hammer can be found on several places on this forum. It is available in either a widely supported Perl version or an even more widely supported shell version. Both also available on my site (follow the lnks in that FAQ page)

BTW GNU date (in GNU coreutils) available at http://hpux.connect.org.uk/hppd/hpux/Gnu/coreutils-5.2.1/ also by HP

procura,

Thank you for that. That's an extremely easy statement to embed in my shell scripts.

Perhaps you're referring to the "HP
Internet Express" package. It mostly
consists of higher-level packages like
Eclipse, Samba, etc. though it does
include a few lower-level items like
bash and vim:

The Linux porting kit and STK might also
contain some GNU tools:
