It's easy as pie to get the date minus one day on opensolaris:
Code:
date -d "-1 day" +"%Y%m%d"
run this command on our crappy Solaris 10 machines however (which I'm guessing doesn't have GNU date running on it) and you get:
Code:
date: illegal option -- d
date: illegal option -- 1
date: illegal option --
date: illegal option -- d
date: invalid argument -- y
usage: date [-u] mmddHHMM[[cc]yy][.SS]
date [-u] [+format]
date -a [-]sss[.fff]
This is so so annoying. I can't put GNU date on these unix machines, so how can I get the date -1 day?
Cheers
