Posting file's modification date?

[Anonymous Monk]

I am listing files in a Directory in a table on a web page. I want to post the Date Modified next to the name of the file. How do I capture the modified date of a file? [e-mail]

You will find a discussion here Find and check timestamps of files. The answer is basically

$mod = (stat "$path/$filename")[9];
 
# this prints result in usual date format
# like -> Tue Jun 12 23:50:10 2001

print scalar localtime $mod; 

If you use Super Search you will find heaps of examples on this topic floating around the monastery. This is also in the Perl FAQ at How do I get a file's timestamp in perl?. If you have not discoverd the Perl FAQ you are missing out on heaps of goodies.

You can use -M to find out the age of the file since the last modification. This is age in days like 6.5321421 etc.

$age = -M $file;

There is a mod_perl gotcha here... The file test operators calculate their deltas based on the "scripts" starting time. Under normal situations this works fine, but with mod_perl it can cause problems, since the starting time may have been weeks ago. (leading to values such as "This file was modified -5.24 days ago") Resetting the $^T variable to the current time will fix this.

$^T = time();
$age = -M $file;

Of course, if it is straight CGI, you don't need to worry about it.
