Re: How to Know how much old my file is

Hello,
is better to use Perl functions when they are! in this case stat is your tool. Modification time is the 9th element of the array returened by that function. Pay some attention to returned time value because they are expressed in seconds from epoch.
Additionally you must be aware of some modification needed, for example, to years (add 1900). see the docs for the localtime function.

Be aware of ~~do not using the module~~(update 16 Sep) to understand the differences between the builtin function and the module: infact the module override the stat function and export a object oriented interface: see Problem with file::stat and Re: File date.

yes you are somehow right. I just not explored yet the possibility of using Path::Tiny even if i have eard very well about it. Anyway i do not dislike the use of low levels: they are the foundamentals, usefull to know and understand, imho. `perl -e "print scalar localtime((stat $ARGV[0])[9])" .
