sum(1)                                                        sum(1)


       NAME
             sum - print checksum and block count of a file

       SYNOPSIS
             sum [-r] file

       DESCRIPTION
             sum calculates and prints a 16-bit checksum for the named
             file, and also prints 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.  The
             option -r causes an alternate algorithm to be used in
             computing the checksum.

       FILES
             /usr/lib/locale/locale/LC_MESSAGES/uxdfm
                   language-specific message file [See LANG on environ(5).]

       REFERENCES
             wc(1)

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