To begin, we use the command below to display the number of seconds since the epoch began on Jan 1, 1970. This is how Linux stores dates and times. $ date +%s 1719337777 To convert this number from the number of seconds to the number of days, you would do this: $ days=`expr 1719337777 / 60 / 60 / 24` 19899 This divides the number of seconds by the number of seconds per minute, minutes per hour and hours per day. And, if you’re not confident about the result, you can convert it to the number of years and see a number that is easier to confirm. $ expr 19899 / 36554 Jul 15, 2024 1 minsLinux How to use the pv command Jul 09, 2024 2 minsLinux How to use the stat command Jun 27, 2024 2 minsLinux The SL command easter egg Jun 27, 2024 1 minsLinux See all videosPodcasts podcastsDesign Your Networks for the Internet of the FutureRegardless of unique business goals, every service provider and enterprise relies on new technologies to help them achieve their intended business outcomes, like growing revenue, reducing costs, and mitigating risks for themselves and their customers.
