.B cksum *.c
# Display CRC and size of \fI.c\fP files
.SH DESCRIPTION
.PP
.I Cksum
calculates and writes to standard output the 32-bits CRC of the input
.I files ,
or of stdin if no
.I files
were specified. The size in bytes of each
.I file
will be displayed after a space. The name of each
.I file
will be displayed after another space.

.BR crc (1),
.BR sum (1).

.TH SUM 1
.SH NAME
sum \- compute the checksum and block count of a file
.SH SYNOPSIS
\fBsum \fIfile\fR
.br
.de FL
.TP
\\fB\\$1\\fR
\\$2
..
.de EX
.TP 20
\\fB\\$1\\fR
# \\$2

.SH EXAMPLES
.TP 20
.B sum /user/ast/xyz
# Checksum \fI/user/ast/xyz
.SH DESCRIPTION
.PP
.I Sum
computes the checksum of one or more files.
It is most often used to see if a file copied from another machine has
been correctly received.
This program works best when both machines use the same checksum algorithm.
See also \fIcrc\fR.
.SH "SEE ALSO"
.BR cksum (1),
.BR crc (1).
