use epoch arithmetic
you can perform epoch arithmetic Code:
1 day = 86400 secs 15 days = 1296000 secs today's date Code:
$ date Fri Mar 22 06:18:17 EDT 2013 script to calculate date after 15 days Code:
today=`date +%s`;let after_15=today+1296000; date -d "@${after_15}"o/p Code:

Hi, I am getting below errors Code:
`date +%s`;let after_15=today+1296000; date -d "@${after_15}"
date: bad format character - s
ksh: after_15=today+1296000: bad number
date: illegal option -- d
Usage: date [-u] [+format]
date [-u] [mmddhhmm[[cc]yy]]
date [-a [-]sss.fff]this is Working in Bash shell but not in ksh Please provide me alternate solutions Thanks, Krupa Last edited by Franklin52; 03-26-2013 at 05:40 AM.. Reason: Please use code tags for data and code samples |
