NAME
       sum - print checksum and block count for a file

SYNOPSIS
       /usr/bin/sum [-r] [file...]

DESCRIPTION
       The sum lists the checksum for each of its file arguments. The standard
       input is read if there are no file arguments.

OPTIONS
       The following option is supported:

       -r    Use  an  alternate (machine-dependent) algorithm in computing the
             checksum.


OPERANDS
       The following operands are supported:

       file    A path name of a file. If no files are named, the standard  in‐
               put is used.


ENVIRONMENT VARIABLES
       See  environ(7) for descriptions of the following environment variables
       that affect the execution of sum: LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS
       The following exit values are returned.

       0      Successful completion.


       > 0    An error occurred.


ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:

       tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) ATTRIBUTE  TYPEAT‐
       TRIBUTE VALUE _ Availabilitysystem/core-os _ CSIEnabled


SEE ALSO
       cksum(1), digest(1), getconf(1), wc(1), libmd(3LIB), attributes(7), en‐
       viron(7)

DIAGNOSTICS
       Read error is indistinguishable from end of file on most devices. Check
       the block count.

NOTES
       Portable  applications  should  use cksum(1). The default algorithm for
       this command is defined in the POSIX standard and is  identical  across
       platforms.


       The  sum  command  is  typically used to quickly compare a suspect file
       against a trusted version of the same, such as  to  ensure  that  files
       transmitted  over  noisy  media arrive intact. However, this comparison
       cannot be considered cryptographically secure. When compatibility  with
       existing  sum usage or values is not required, the digest(1) command is
       recommended instead, as it provides more modern and secure algorithms.


       In previous releases of Solaris, there was a /usr/ucb/sum that returned
       a different checksum than the sum command described here due to differ‐
       ent blocksizes and algorithms used. The command sum uses 512 byte block
       sizes while /usr/ucb/sum used 1024 byte block sizes.
