Re: date command problem

Try the following command at your unix prompt:

perl -e 'print localtime(time() - 86400) . "\n" '

If your unix machine has Perl installed, then it will work.

Check below link Use the date_calc script to calculate the date you need then pass it as a parameter to your script

Re: date command problem

Depending on your environment and your needs it might be easier to grab GNU date (part of coreutils), which lets you do nifty things like "date -d yesterday". Just make sure GNU date isn't in your system-wide PATH or give it a different name so that you don't have any problems with tools that expect HP's date.
