Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Perl one-liner to determine number of days since the Unix epoch

There are some environments that use this value for password and account expiration. It's helpful to be able to quickly determine the number of days since the Unix epoch (dse) when working directly with the configuration files as an administrator.

Alternatives

There is 1 alternative - vote for the best!

What others think

This is another way to do it:

perl -le 'print int time/(60*60*24)'

Or in bash:

echo $(($(date +%s)/86400))

I like the BASH method, but there's no guarantee that the GNU date command will be available on any given system.
