iYesterday I discovered a nice feature of ksh93: It has error.host 1
isupport for date manipulation with printf (ksh's builtin). error.host 1
i error.host 1
iSee this post: error.host 1
i
http://blog.fpmurphy.com/2008/11/korn-shell-93-secrets-1.html error.host 1
i error.host 1
iExamples (from the page above): error.host 1
i error.host 1
i$ printf "%Tn" "2:00pm yesterday" error.host 1
iFri Mar 21 14:00:00 EST 2008 error.host 1
i error.host 1
iprintf "%(%a)Tn" "final day Feb 2008" error.host 1
iFri error.host 1
i error.host 1
i$ printf "%(%D)Tn" "3rd wednesday may 2008" error.host 1
i05/21/08 error.host 1
i error.host 1
i$ printf "%(%D)Tn" "4 weeks ago" error.host 1
i02/18/08 error.host 1
i error.host 1
iIt also understands crontab format: error.host 1
i$ printf "%Tn" "0 0 1,15 * 1" error.host 1
iMon Sep 1 00:00:00 EDT 2008 error.host 1
i error.host 1
iAccording to Glenn Fowler[1] it's better to write the dates error.host 1
ilike this: error.host 1
i error.host 1
i$ printf "%(%K)Tn" "Sept 23 2009 noon" error.host 1
i2009-09-23+12:00:00 error.host 1
i error.host 1
i$ printf "%(%K)Tn" "Sept 23 2009 noon 90 days" error.host 1
i2009-12-22+12:00:00 error.host 1
i error.host 1
i$ printf "%(%K)Tn" "Sept 23 2009 noon 90 days hence" error.host 1
i2009-12-22+12:00:00 error.host 1
i error.host 1
i$ printf "%(%K)Tn" "Sept 23 2009 noon 90 days ago" error.host 1
i2009-06-25+12:00:00 error.host 1
i error.host 1
iThat is, with the "reference date first" and the modifiers. error.host 1
i error.host 1
i-- error.host 1
i error.host 1
i[1] error.host 1
