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.
