+The command
+.B filesize
+displays the number of bytes in each
+.IR file .
+.II wc
+.II stat()
+It is much faster than the COHERENT command
+.B wc
+because it uses the system call
+.B stat()
+to get the number from the i-node table,
+rather than counting the bytes in the file.
+.PP
+If you ask
+.B filesize
+to size only one file,
+it sends one number to the
+standard output.
+This number can be assigned to a shell variable.
+With more than one
+.IR file ,
+it produces a table of sizes.
+.SH Example
+The following command returns the size of file
+.BR filesize.1 ,
+which holds the ``raw'' form of what you are reading:
+.DM
+	filesize filesize.1
+.DE
+.PP
+This displays one value on the standard output, e.g.:
+.DM
+	532
+.DE
+.PP
+The following command asks for the size of files
+.B ascii.1
+and
+.BR filesize.1 :
+.DM
+	filesize ascii.1 filesize.1
+.DE
+.PP
+This form of the command returns a tabular output, e.g.:
+.DM
+  Offset        Filename
+--------        --------
+     464        ascii.1
+     532        filesize.1
