NAME
sum - calculate a sum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2 package require sum ?1.0? ::crc::sum ?-format format? message ::crc::sum ?-format format? -filename file
DESCRIPTION
This package provides a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data. The BSD sum algorithm is used by default but the SysV algorithm is also available.
COMMANDS
::crc::sum ?-format format? message ::crc::sum ?-format format? -filename file The command takes string data or a file name and returns a checksum value calculated using the sum(1) algorithm. The result is formatted using the format(n) specifier provided or as an unsigned integer (%u) by default.
OPTIONS
-filename name Return a checksum for the file contents instead of for parameter data. -format string Return the checksum using an alternative format template.
EXAMPLES
% crc::sum "Hello, World!" 37287 % crc::sum -format 0x%X "Hello, World!" 0x91A7 % crc::sum -file sum.tcl 13392
