Hi,

any idea how to add hours to current date in unix.

thanks in advance

2

This works on my GNU bash:

date -d "+5 hours"
3

didn't worked on my solaris

date -d "+5 hours"
date: illegal option -- d
usage:  date [-u] mmddHHMM[[cc]yy][.SS]
        date [-u] [+format]
        date -a [-]sss[.fff]

This adds 5 hours to current time.

perl -e '$x=localtime(time+(5*3600));print $x'

Hi Shukla,

There is nothing about shell. you are using the Gnu Date. But the questioner asked solution for solaris machine. (ie., NO GNU DATE in solaris )

Was asking for shell used to present script ..
Thnx .
