CRC(1)							      General Commands Manual							    CRC(1)

NAME

       crc - print the checksum of the file data

SYNOPSIS

       crc file ...

EXAMPLES

       crc *.c		   # Print checksums of all the C programs

DESCRIPTION

       The  checksum of each argument is computed and printed, along with the file length and its name, one file per line.  This program is useful
       for seeing if a file transmitted to another machine has arrived correctly.  It is conceptually similar  to  sum,  except  that  it  uses  a
       stronger checksum algorithm and also prints the length.

SEE ALSO

       cksum(1), sum(1).

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
