How do I convert an epoch timestamp to a human readable format on the cli? I think there's a way to do it with date but the syntax eludes me (other ways welcome).
How do I convert an epoch timestamp to a human readable format on the cli?
command line;shell;date
On *BSD:date -r 1234567890On Linux (specifically, with GNU coreutils 5.3):date -d @1234567890With older versions of GNU date, you can calculate the relative difference to the UTC epoch:date -d '1970-01-01 UTC + 1234567890 seconds'If you need portability, you're out of luck. The only time you can format with a POSIX shell command (without doing the calculation yourself) line is the current time. In practice, Perl is often available:perl -le 'print scalar localtime $ARGV[0]' 1234567890
