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 #- Copyright (c) HerongYang.com. All Rights Reserved. # ($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:
herong> 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 =
