plus3days=$( date '+%Y-%m-%d %H:%M:%S'
-D '%s'
-d $((`date '+%s'` + 3*24*60*60))
)
Aha - I didn't know you could get date to just chuck out "seconds since
epoch"
so
1. get seconds since epoch, add seconds as desired
2. tell dat you will be giving it a time in "seconds since epoch" format
3. ask for a date string in a format suitable for touch
lovely - thank you!
I wish I was clever...
