sumdir(1) sumdir(1)
NAME
sumdir - sum and count characters in the files in the given
directories
SYNOPSIS
sumdir [directories]
DESCRIPTION
sumdir calculates and prints a 16-bit checksum for the named
file, and also prints the number of characters in the file.
It is typically used to look for bad spots on the file
system, or to validate a file transmitted over some
transmission line. The output from this program differs
from the output from the sum(1) program in that sumdir
prints the number of characters rather than the number of
blocks in the file.
sumdir provides a recursive checksum of all files in the
specified directory.
EXAMPLE
sumdir man1
produces the checksum and the character count of the files
in the directory man1.
