statSee the current Perl documentation for stat. Here is our local, out-dated (pre-5.6) version: stat - get a file's status information
stat FILEHANDLE stat EXPR stat
Returns a 13-element list giving the status info for a file, either the file opened via
FILEHANDLE, or named by
EXPR. If
EXPR is omitted, it stats
($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size, $atime,$mtime,$ctime,$blksize,$blocks) = stat($filename); Not all fields are supported on all filesystem types. Here are the meaning of the fields:
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 since the epoch 9 mtime last modify time since the epoch 10 ctime inode change time (NOT creation time!) 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.) If stat is passed the special filehandle consisting of an underline, no stat is done, but the current contents of the stat structure from the last stat or filetest are returned. Example:
if (-x $file && (($d) = stat(_)) && $d < 0) { print "$file is executable NFS file\n"; } (This works on machines only for which the device number is negative under NFS.)
In scalar context, stat() returns a boolean value indicating success or failure, and, if successful,
sets the information associated with the special filehandle |
