Just a side note: I like using %F for this type of string. > This works perfect for all dates I used so far, apart from a (strangely > enough) 20081026 > date -d "20081026 1 days" +%Y%m%d > returns the same datecode: 20081026 You probably want to do the date calculation at noon to avoid problems near time change since one day is really 24 hours. And working in UTC is safer. Try these: date -u -d "2008-10-26 12:00 UTC +1 days" +%Y%m%d date -u -d "20081026 12:00 +0000 1 days" +%Y%m%d Please also see this FAQ item as you may be experiencing one of the problems described there. http://www.gnu.org/software/coreutils/faq/#The-date-command-is-not-working-right_002e And the documentation here: info coreutils "General date syntax" Bob _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
