Date difference between 2 dates in 'yyyy-mm-dd hh:mm:ss' format
Hi all,

I know this may have already been asked but hey ho...

i have two dates in the 'yyyy-mm-dd hh:mm:ss' format.

'2009-01-03 01:00:00'
'2009-04-05 00:00:00'

How can i, in shell script determine their differences?

Please note, the time may not be available, so please suggest both ways as i may have dates in this format too:

i.e. for when i only have:

'2009-01-03'
'2009-04-05'

Go here and look in the sample chapter for diffdate. (Hi Chris)

This might be the key command you need:

Code:
date +%s -d"2009-01-03"

will return seconds since epoch
do that twice, once for each time, storing to variables
then math will give you # seconds between two dates
finally, divide by seconds in a day
voila -- # days between two dates
