print checksum and byte count of a file
cksum [file ... ]
calculates the 32-bit checksum of each file, and prints the
result to stdout.
If no file is specified, cksum
reads from stdin.
For each file, cksum reads
the file and calculates the checksum
in a machine-independent way, then prints the
checksum, number of bytes, and
filename, each separated by a space.
The output is one line per file.
If the input is stdin, then the filename is not printed.
language-specific message file. See LANG on
If an error is encountered, cksum will print a diagnostic
message, skip the file in which the error occurred, and continue
with the next file, returning a non-zero result.
If no errors occur, the exit value will be zero.
This command is a POSIX.2 command, and should be used in
preference to the old System V alternative, sum, since
cksum is both standard and more accurate.
Like sum, the main purpose of this command is to verify that
files transferred across a suspect medium are correct, by comparing the
results of cksum for the source and destination files.
This command has been updated to handle files greater than 2GB.
