stat() - Returns File Statistics

This section provides a tutorial example on using stat() to return many statistics of the specified file, including file size, creation time, and last modification time.

Instead of using individual file test operators, you can use the stat() function to return a number of statistics of a file. The following tutorial program shows you how to use stat():

#- stat.pl

#
   ($file) = @ARGV;
   die "Missing file name.\n" unless $file;
   ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,
      $atime,$mtime,$ctime,$blksize,$blocks) = stat($file);
   print "dev = $dev\n";
   print "ino = $ino\n";
   print "mode = $mode\n";
   print "nlink = $nlink\n";
   print "uid = $uid\n";
   print "uid = $uid\n";
   print "gid = $gid\n";
   print "rdev = $rdev\n";
   print "size = $size\n";
   print "atime = $atime\n";
   print "mtime = $mtime\n";
   print "ctime = $ctime\n";
   print "blksize = $blksize\n";
   print "blocks = $blocks\n";
   exit;

If you run it on a Windows system, you will get something similar to this:

>stat.pl stat.pl
dev = 3
ino = 0
mode = 33206
nlink = 1
uid = 0
uid = 0
gid = 0
rdev = 3
size = 622
atime = 1069622049
mtime = 1069621972
ctime = 1069621496
blksize =
blocks =
