Obtain UNIX epoch time using bash
Obtaining the UNIX epoch time using bash is easy. Use the build-in date command and instruct it to output the number of seconds since 1970-01-01 00:00:00 UTC. You can do this by passing a format string as parameter to the date command. The format string for UNIX epoch time is ‘%s’.
