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

perl -e 'printf qq{%d\n}, time/86400;'
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.

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.
