Hammer & Screwdriver Need difference between days
Hi,

I am not comfortable with dates and I fail to crack this.

I have two strings

Code:
Date1="Apr 22 23:59:59 2016 GMT"
Date2="Dec  1 15:08:40 UTC 2015"

I need to find the difference in days between the two dates which in this example is approx 140 days.

Is there an easy way to get the difference in days ?

This depends on your system. What be the OS, shell, date versions?

I'm on Linux x86_64 GNU/Linux. I can use Bash or C shell.
Code:
uname -r
2.6.32-431.5.1....

rpm -qa | grep date
python-dateutil-1.4.1-6.el6.noarch

Try this bashism:
Code:
echo $((($(date -d"Apr 22 23:59:59 2016 GMT" +%s) - $(date -d"Dec 1 15:08:40 UTC 2015" +%s)) / 86400))
143
