|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.BR cksum
|
||||
utility writes to the standard output three whitespace separated
|
||||
fields for each input file.
|
||||
These fields are a checksum
|
||||
.BR CRC ,
|
||||
the total number of octets in the file and the file name.
|
||||
If no file name is specified, the standard input is used and no file name
|
||||
is written.
|
||||
.PP
|
||||
The
|
||||
.BR sum
|
||||
utility is identical to the
|
||||
.BR cksum
|
||||
utility, except that it defaults to using historic algorithm 1,
|
||||
described below.
|
||||
It is provided for compatibility.
|
||||
You can either install the
|
||||
.BR sum
|
||||
program (which has the same content as the
|
||||
.BR cksum
|
||||
program file) or create a
|
||||
.IR gsh (1)
|
||||
alias that invokes
|
||||
.BR cksum :
|
||||
.nf
|
||||
alias sum "cksum -o 1"
|
||||
.fi
|
||||
.PP
|
||||
The program options are as follows:
|
||||
.RS
|
||||
.IP \fB-o\fR
|
||||
Use historic algorithms instead of the (superior) default one.
|
||||
.PP
|
||||
.RS
|
||||
Algorithm 1 is the algorithm used by historic
|
||||
systems as the
|
||||
.BR sum (1)
|
||||
algorithm and by historic
|
||||
systems as the
|
||||
.BR sum
|
||||
algorithm when using the
|
||||
.BR -r
|
||||
option.
|
||||
This is a 16-bit checksum, with a right rotation before each addition;
|
||||
overflow is discarded.
|
||||
.PP
|
||||
.RS
|
||||
Algorithm 2 is the algorithm used by historic
|
||||
systems as the
|
||||
default
|
||||
.BR sum
|
||||
algorithm.
|
||||
This is a 32-bit checksum, and is defined as follows:
|
||||
.nf
|
||||
s = sum of all bytes;
|
||||
r = s % 2^16 + (s % 2^32) / 2^16;
|
||||
cksum = (r % 2^16) + r / 2^16;
|
||||
.fi
|
||||
.PP
|
||||
.RS
|
||||
Algorithm 3, a 32-bit checksum, is commonly called the
|
||||
.BR "32bit CRC"
|
||||
algorithm.
|
||||
.PP
|
||||
.RS
|
||||
Algorithms 1 and 2 write the same fields as
|
||||
the default algorithm except the size of the file is
|
||||
expressed in blocks.
|
||||
For historic reasons, the block size is 1024 for algorithm 1 and 512
|
||||
for algorithm 2.
|
||||
Partial blocks are rounded up.
|
||||
.RE
|
||||
.PP
|
||||
The default
|
||||
.BR CRC
|
||||
used is based on the polynomial used for
|
||||
.BR CRC
|
||||
error checking
|
||||
in the networking standard
|
||||
POSIX-3.
|
||||
The
|
||||
.BR CRC
|
||||
checksum encoding is defined by the generating polynomial:
|
||||
.PP
|
||||
.nf
|
||||
G(x) = x^32 + x^26 + x^23 + x^22 + x^16 + x^12 +
|
||||
x^11 + x^10 + x^8 + x^7 + x^5 + x^4 + x^2 + x + 1
|
||||
.fi
|
||||
.PP
|
||||
Mathematically, the
|
||||
.BR CRC
|
||||
value corresponding to a given file is defined by
|
||||
the following procedure:
|
||||
.PP
|
||||
.RS
|
||||
The
|
||||
.BR n
|
||||
bits to be evaluated are considered to be the coefficients of a mod 2
|
||||
polynomial M(x) of degree
|
||||
.BR n-1 .
|
||||
These
|
||||
.BR n
|
||||
bits are the bits from the file, with the most significant bit being the most
|
||||
significant bit of the first octet of the file and the last bit being the least
|
||||
significant bit of the last octet, padded with zero bits (if necessary) to
|
||||
achieve an integral number of octets, followed by one or more octets
|
||||
representing the length of the file as a binary value, least significant octet
|
||||
first.
|
||||
The smallest number of octets capable of representing this integer are used.
|
||||
.PP
|
||||
.RS
|
||||
M(x) is multiplied by x^32 (i.e., shifted left 32 bits) and divided by
|
||||
G(x) using mod 2 division, producing a remainder R(x) of degree <= 31.
|
||||
The coefficients of R(x) are considered to be a 32-bit sequence.
|
||||
The bit sequence is complemented and the result is the CRC.
|
||||
.PP
|
||||
.RS
|
||||
The default calculation is identical to that given in pseudo-code
|
||||
in the
|
||||
article "Computation of Cyclic Redundancy Checks Via Table Lookup"
|
||||
by
|
||||
Dilip V. Sarwate,
|
||||
.IR "Communications of the ACM" ", August 1988."
|
||||
.RE
|

.PP
|
||||
The
|
||||
.BR cksum
|
||||
and
|
||||
.BR sum
|

utilities exit 0 on success, and >0 if an error occurs.
|

.SH VERSION
|
||||
This manual page documents
|
||||
.BR cksum
|
||||
version 2.0.
|
||||
.SH ATTRIBUTIONS
|
||||
This command was ported from FreeBSD source code
|
||||
for distribution with GNO/ME 2.0.6.
|
||||
.SH HISTORY
|
||||
A version of
|
||||
.BR sum
|
||||
translated from GNU code in 1991 by Marek Pawlowski was distributed with
|
||||
earlier releases of GNO. Unfortunately, as that version reads files it
|
||||
translates carriage return characters into new line characters. To use
|
||||
.BR cksum
|
||||
to calulate a checksum that matches the old
|
||||
.BR sum ,
|
||||
use
|
||||
.IR tr (1)
|
||||
to translate the input stream. For example,
|
||||
.nf
|
||||
tr '\\r' '\\n' < filename | cksum -o 1
|
||||
.fi
|
||||
.SH STANDARDS
|
||||
The
|
||||
.BR cksum
|
||||
utility is expected to conform to
|
||||
POSIX-2.
