You should stat it.

Excerpts from stat(2) :

       int fstat(int filedes, struct stat *buf);

       These  functions  return  information about the specified file.  You do
       not need any access rights to the file to get this information but  you
       need  search rights to all directories named in the path leading to the
       file.

       They all return a stat structure, which contains the following fields:

              struct stat {
                  dev_t         st_dev;      /* device */
                  ino_t         st_ino;      /* inode */
                  mode_t        st_mode;     /* protection */
                  nlink_t       st_nlink;    /* number of hard links */
                  uid_t         st_uid;      /* user ID of owner */
                  gid_t         st_gid;      /* group ID of owner */
                  dev_t         st_rdev;     /* device type (if inode device) */
                  off_t         st_size;     /* total size, in bytes */
                  blksize_t     st_blksize;  /* blocksize for filesystem I/O */
                  blkcnt_t      st_blocks;   /* number of blocks allocated */
                  time_t        st_atime;    /* time of last access */
                  time_t        st_mtime;    /* time of last modification */
                  time_t        st_ctime;    /* time of last change */
              };

If anyone would come after me, he must deny himself and take up his
cross and follow me.  For whoever wants to save his life will lose it,
but whoever loses his life for me and for the gospel will save it.  What
good is it for a man to gain the whole world, yet forfeit his soul?  Or
what can a man give in exchange for his soul?
