How do I get a file's last modified time in Perl?

Question

Suppose I have a filehandle $fh. I can check its existence with -e $fh or its file size with -s $fh or a slew of additional informati

Answer 1

my @array = stat($filehandle);

The modification time is stored in Unix format in $array[9].

Or explicitly:

my ($dev, $ino, $mode, $nlink, $uid, $gid, $rdev, $size,
    $atime, $mtime, $ctime, $blksize, $blocks) = stat($filepath);

  0 dev      Device number of filesystem
  1 ino      inode number
  2 mode     File mode  (type and permissions)
  3 nlink    Number of (hard) links to the file
  4 uid      Numeric user ID of file's owner
  5 gid      Numeric group ID of file's owner
  6 rdev     The device identifier (special files only)
  7 size     Total size of file, in bytes
  8 atime    Last access time in seconds since the epoch
  9 mtime    Last modify time in seconds since the epoch
 10 ctime    inode change time in seconds since the epoch
 11 blksize  Preferred block size for file system I/O
 12 blocks   Actual number of blocks allocated

The epoch was at 00:00 January 1, 1970 GMT.

More information is in stat.
