What have you tried? There's lots of documentation out there, and search engines to find the documentation and lots of other examples. Perl 6 projects - links to (nearly) everything that is Perl 6.	[reply]

Following on from moritzs reply, a combination of glob, stat, sort & Date::Calc (with suitable glue code) should suffice ... I'll show you my code, if you show me yours :-D A user level that continues to overstate my experience :-))	[reply]

What OS? unix doesn't track file creation times normally, so Perl doesn't provide a method to get it on systems where it might be supported. A module on CPAN might.	[reply]

I don't know what version of UNIX you run but maybe you need to check out `man ctime`	[reply] [d/l]

I think you mean the `st_ctime` argument of `stat`. You should follow your own advise: `st_ctime` Time when file status was last changed (inode data modification). Changed by the chflags(2), chmod(2), chown(2), creat(2), link(2), mkdir(2), mkfifo(2), mknod(2), rename(2), rmdir(2), symlink(2), truncate(2), unlink(2), utimes(2), write(2) and writev(2) system calls. `$ touch a $ perl -MFile::stat -wle'print "".localtime( stat("a")->ctime )' Fri Aug 21 13:31:40 2009 $ sleep 2 $ perl -MFile::stat -wle'print "".localtime( stat("a")->ctime )' Fri Aug 21 13:31:40 2009 $ chmod go= a $ perl -MFile::stat -wle'print "".localtime( stat("a")->ctime )' Fri Aug 21 13:32:25 2009` [download] I don't know what version of UNIX you run The man page is from FreeBSD 7.2. You can view the man pages for about 100 different systems if you follow the link above, and I'm sure you'll find similar results for all of them. The example was executed on Debian Linux (etchnhalf)	[reply] [d/l] [select]

`$ man -f ctime asctime, asctime_r, ctime, ctime_r, difftime, gmtime, gmtime_r, localtime, localtime_r, mktime, timegm, timelocal (3) - convert date and time to ASCII` [download] This has nothing about creation time in it. Look here and stat(2) for more details about the lack of creation time. There is mtime (modified - file data change), atime (access time), and ctime (changed time - inode data modifcation).
