Getting previous day's date in Unix
I cannot do an exact test on solaris. but on linux this works for getting last day(yesterday):
kent$ date -d'yesterday' +%Y%m%d20130520so you just type "yesterday", you don't have to do something special with date. It is cool, isn't it?
On Solaris simply use GNU date rather than the Solaris version. Access with gdate as opposed to date. Then you simply do
gdate -d'yesterday' +%Y%m%dYour Solaris SysAdmin may have given you a crippled host where GNU coreutils (GNU date is part of that package) are not installed by default. Shame on him.
More info on what a Solaris host should look like on this link. The link has info for both Solaris 10 and Solaris 11.
For Unix OS, this works fine for me
date +%Y/%m/%d --date="yesterday"
