LEARN ABOUT SUNOS
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. SunOS 5.10 7 Nov 1995 sum(1)
