To get the date-string in bash: echo “Current: ” $(date +”%Y”-“%m”-“%d”T”%H”-“%M”-“%S”) echo “+2 min : ” $(date –date=”@$(($(date +%s)+120))” +”%Y”-“%m”-“%d”T”%H”-“%M”-“%S”) prints Current: 2014-09-10T15-58-15 +2 min : 2014-09-10T16-00-15 Read the time from string and print +2min string str=”2014-09-10T15-58-15″ new=$(date –date=”@$(($( IFS=”-T” read y m d H M S <<< “$str”;date –date=”$y-$m-${d}T$H:$M:$S” +%s )+120))” +”%Y”-“%m”-“%d”T”%H”-“%M”-“%S”) echo “From … Read more
