Question

I need something simple like date, but in seconds since 1970 instead of the current date, hours, minutes, and seconds.

date doesn\'t seem t

Answer 1

use this bash script (my ~/bin/epoch):

#!/bin/bash

# get seconds since epoch
test "x$1" == x && date +%s && exit 0

# or convert epoch seconds to date format (see "man date" for options)
EPOCH="$1"
shift
date -d @"$EPOCH" "$@"
