sum

sum(1)								   User Commands							    sum(1)

NAME

       sum - print checksum and block count for a file

SYNOPSIS

       sum [-r] [file...]

DESCRIPTION

       The   sum utility calculates and prints a 16-bit checksum for the named file and the number of 512-byte blocks in the file. It is typically
       used to look for bad spots, or to validate a file communicated over some transmission line.

OPTIONS

       The following options are 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 input is used.

USAGE

       See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

ENVIRONMENT VARIABLES

       See environ(5) 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(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWesu			   |
       |CSI			     |enabled			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       cksum(1), sum(1B), wc(1), attributes(5), environ(5), largefile(5)

DIAGNOSTICS

       "Read error" is indistinguishable from end of file on most devices; check the block count.

NOTES

       Portable applications should use cksum(1).

       sum and usr/ucb/sum (see sum(1B)) return different checksums.
