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 for-
matted 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
